Hello and Welcome
to Renew

Hello and welcome to Renew. We have been close friends and professional colleagues for several years now. We both have many years of daily experience treating patients with IV Ketamine. Through our work in the hospital Emergency Departments, we see firsthand the shortcomings and failures of traditional medicine for the treatment of mental health and chronic pain. We have developed a novel treatment program that can change your life in a safe and effective way.

We believe in the inherent medicinal properties of Ketamine and how these effects can be made exponentially greater with a robust integrative psychotherapy program.  We can’t wait to work with you to help you Renew your outlook on life.

Dr. Tanya Dall

Hello, my name is Dr. Tanya Dall. I am a Board Certified Emergency Medicine Physician. I was raised in a military, and completely non-medical, family. My interest in medicine was piqued in the 5th grade, while watching the hit TV show “TLC-Trauma; Life in the ER.” I was instantly fascinated by how the human body, specifically the brain, functioned. This interest has continued, as I have now shifted to focus on how psychedelic treatments can heal the mind.

I studied Human Physiology at the University of Arizona. I went on to obtain my Medical Degree at Georgetown University. I was blessed with the opportunity to return home to the West Coast to train at UC Irvine for my Emergency Medicine residency training.

I now work on staff in the Emergency Department at the Level 2 Trauma center Providence Mission Hospital, in Mission Viejo, CA. I also travel occasionally to rural Bisbee and Douglas, AZ to offer care to these underserved communities. I specialize in the safe and effective use of Ketamine in my daily practice. 

After many years of practicing Medicine, I realize the failures of Traditional Medicine to treat mental health and chronic pain. After much research, I believe psychedelic medicine is the future of treating such conditions.

Welcome, and I cannot wait to meet you and share more about how Renew can help!

Dr. Justin Yanuck

Hi, my name Is Dr. Justin Yanuck and I am board certified in both Emergency Medicine (University of California, Irvine) and Pain Medicine (Harvard Massachusetts General Hospital). My background is a bit atypical for most Emergency Medicine doctors, but throughout my residency I felt for many chronic pain patients that we would see in the emergency room, I didn’t quite know how to best help them. I decided to start doing research in the world of chronic pain, and this led me to pursuing a fellowship where I devoted an entire year to learning about pain management. I practiced in a private pain medicine clinic after this training, and throughout that time I came across a subset of patients that no matter what intervention you would do for them, or medication I would start, they wouldn’t get any robust relief.

While working in the emergency department, which I continue to do to this day, I have had extensive experience working with Ketamine for multiple reasons: procedural sedation, reduction in acute pain, and for calming hyperactive patients. Over the years, I started to become interested in the possibility that Ketamine could be used not just for these reasons but possibly other diseases as well. I’ve since dived into the existing literature on Ketamine as well as other emerging therapeutics including Psilocybin, LSD, MDMA and I am convinced that these medications can really help people who are suffering. For now, Ketamine is the only legal medication to be utilized and is thus where my primary focus has been, and having heard from my own patients as well as reviewing the literature, I am convinced that Ketamine assisted therapy, for the right patient, can be a transformational treatment option.

Dr. David Richter

Seal Beach Medical Director

Hi, my name is Dr. David Richter and I am a Board Certified Emergency Medicine Physician. Since immigrating to the United Stated from the Czech Republic at the age of eighteen, I have had many varied interests and have always felt great compassion towards healing others.
During my medical training at UC Irvine and USC, along with my current practice in the
Emergency Department, I became more interested in integrative approaches to help my patients heal by addressing both the body and mind in uniform. Working in the ED has helped me to understand many of the pitfalls of our current care model which tends to focus on body systems rather than the body as a whole. I was mainly realizing the gaps in mental healthcare, which are increasingly reflected in growing ED visits for some of the most vulnerable patients, and our systemic inability to address them. Moreover, current psychotherapies are frequently not able to help patients that suffer from rebound depressive symptoms, generalized anxiety, PTSD, and other psychological disorders. With my growing passion to understand these processes better, I delved into research and further specialized training using Ketamine Assisted Psychotherapy (KAP). Ketamine is a medication that I have extensive experience using in the ED, and it is showing great results in augmenting mental health care. I have taken the formalized Fluence certificate program in KAP and continue to educate myself with Multidisciplinary Association of Psychedelic Studies (MAPS) workshops and seminars. Learning alongside many of the leaders in this field, paired with personal experiences with patients, I have gained a new appreciation for this medication when used in harmony with proper therapeutic techniques. I am ever more hopeful to help people discover their own inner healing intelligence on their path to mending.

Meet the Therapists


Sabrina Owen

Hello, my name is Sabrina Owen. I have been licensed in California as Marriage and Family Therapist since 1999. After growing up watching a family member struggle to find effective mental health treatment, I pursued a career in psychology – receiving my BA in psychology and my MA in counseling psychology. To further my practice, I stay up to date on the recent developments in mental health care. One of the most exciting advancements is the use of psychedelic treatments.

As I learned about the effectiveness of psychedelics in clinical trials and the need for psychedelic-informed and trained clinicians, I knew this was what I wanted to do. I completed a one-year psychedelic integration certificate program through Fluence in 2021, a six-month rater adherence training program from MAPS (Multidisciplinary Association for Psychedelic Studies) and an intensive ketamine three-day training at a well-known ketamine clinic.

Today, I provide compassionate, trauma-informed, and neuroscience-based psychotherapy. In addition to my experience providing psychedelic preparation, integration and harm reduction, my clients benefit from my over 30 years of professional experience and advanced training in DBT (Dialectical Behavioral Therapy), EMDR (Eye Movement Desensitization and Reprocessing), and most recently training in CIMBS (Complex Integration of Multiple Brain Systems). I look forward to working together to assist in your healing and well-being.

Kai Lewis

My name is Kai Lewis (they/he) and I am a CA Licensed Marriage and Family Therapist.  Since 2019, I have been combining evidence-based therapeutic interventions with real world applicability to provide therapy for individuals, relational units, and groups.  I have a holistic and collaborative approach to mental health care that incorporates mind, body, and lifestyle as it relates to you- a unique individual.  

After receiving my undergraduate degree in Psychology from the California Polytechnic University of Pomona, I attended the University of Southern California for my Master’s of Science in Marriage and Family Therapy.  Throughout my education, I have been involved in research labs surrounding the mind body connection, including cognitive language processing, social-relational communication, and nutritional effects on mental health.  

There is not a one-size-fits all approach to mental health; I value assisting patients in exploring all options available for their care, going beyond traditional talk therapy.  After reading emerging research on ketamine’s high efficacy rate and ability to facilitate transformational results as part of treatment for certain mental health experiences, I knew this is something I wanted to offer as part of holistic mental health care.  

In 2022, I completed Fluence’s Ketamine Assisted Therapy training and the 2022 Sana Symposium Conference focused on the intersectionality of ketamine and mental health care.  I also regularly attend workshops, such as through MAPS (Multidisciplinary Association for Psychedelic Studies), and consume up-to-date literature around psychoactive substances in mental health care treatment.  My approach focuses on harm reduction, preparation, integration, and patient collaboration in exploring mental health care options.  I am also trained in Eye Movement Desensitization and Reprocessing (EMDR) therapy, Somatic Experiencing Therapy, and I am an LGBTQ and Neurodivergent affirming provider.

Maria Lloyd

My name is Maria Lloyd and I’ve been a licensed Marriage and Family Therapist working in private practice since 2001.  I graduated with a B.A. from UC Davis in 1994 and did research for Bob Emmons who ended up writing 4 best selling books on gratitude.  I’m still a believer in the power of gratitude!   I got my M.S. from Fuller School of Psychology in 1998 and my training focused on attachment theory and integrating spirituality with therapy.   I specialize working with highly sensitive people (HSP’s) with treatment resistant depression, anxiety and bipolar disorder.   My office is in Mission Viejo and I see people in person and online.

While building a healthy attachment with clients is still my foundation, over the years I have added many other treatment modalities to enhance treatment, especially those targeting trauma.  I’ve added parts work (IFS) to help clients befriend the parts of themselves that may have protected them growing up but are now maladaptive.  I’ve been trained in Brainspotting, which is an attachment focused EMDR method.  I provide Somatic Experiencing for those needing to reconnect with and heal their bodies.  I find DBT and CBT helpful once clients have processed trauma.  Once I get to know the needs of my client, I tailor treatment and discuss what might work best for them.

After the pandemic, I found many of my depressed clients weren’t getting better.  Their bodies and brains couldn’t recover from the stress and I felt helpless in my work with them.  In 2021, I learned about the amazing benefits of Ketamine-Assisted Psychotherapy.  I was trained through Journey Clinical and completed a psychedelic integration certificate through Fluence.  Since that time, I’ve been utilizing ketamine in sessions with clients and eventually found that the more severe the symptoms, the more IV Ketamine was necessary since it has 100% bioavailability.  I’ve transitioned to partner with Renew because they are great providers that provide a beautiful setting for patients to heal. Neuroplasticity (the ability of the brain to change and heal itself) is heightened up to 72 hours after ketamine is administered.  I find there is so much power to these sessions and witness clients process and integrate trauma more effectively and make lasting changes. I’d love the opportunity to meet and see if we might be a good fit to work together.

Riley RN

Hi, I’m Riley. I am a Registered Nurse and have been working as an Emergency Room RN for 7 years. Prior to beginning my career in nursing, I worked as a psychiatric technician in an inpatient Behavioral Health Unit for 7 years, and I feel I’ve found a true calling in melding the two disciplines. After countless years of watching patients and family members of mine struggle with mental illness and chronic pain disorders with little to no improvement, I began looking into alternative treatment options. That’s where Renew Ketamine Infusion therapy comes in. The opportunity to connect with clients in a relaxed setting, while aiding in the improvement of symptoms and overall wellness brings me so much joy! I look forward to meeting and working with you.


Carrie RN

Hello my name is Carrie and I am a Registered Nurse who has specialized mostly in Emergency Medicine the last 15 years. Prior to the ED, I worked in a Burn ICU at UCI Medical Center. I decided my calling was to be a nurse when I was on a trip to Bangladesh as a teenager to help build an orphanage. I saw firsthand how pursuing medical training could benefit those living in that country. I pursued my nursing degree shortly after and have worked almost 20 years in this field. Even after many years in the ED, I have continued to strive to care for my patients with compassion and kindness, as all humans deserve. I have seen the despair those with mental illness have experienced as they search for ways to find help. I am thrilled to be a part of this team and I look forward to being a part of bringing healing and restoration to others.

Obsessive Compulsive disorder (OCD) is unfortunately resistant to many forms of medical treatment including both medication and therapy.

Ketamine has been shown to be an effective, fast acting, safe option for patients with OCD. Over the course of the Ketamine infusions (2-4 weeks) neuroplasticity can lead to a change or abatement in the intrusive, repetitive thoughts and behaviors that typify OCD.

When combined with our unique post infusion integration process, patients with severe OCD can see profound relief of their symptoms.

Chronic Pain

“There is extensive research currently being done on this topic. I can say from personal experience as a practicing Board Certified Pain Medicine Physician, I have had patients with chronic pain, including fibromyalgia, who have had significant relief of their symptoms with Ketamine assisted therapy. With that said, Ketamine assisted therapy will definitely not work for everyone with chronic pain, and each patient will require a thorough evaluation to ensure they are an adequate candidate for a trial of Ketamine assisted therapy for relief of their chronic pain” -Dr. Justin Yanuck.

The current evidence of Ketamine assisted therapy for chronic pain is fairly mixed. The majority of studies only looked at ketamine infusion without any assisted psychotherapy.

Ketamine has the ability to lead to relief on its own (and the mechanisms for this have been well studied). We feel quite strongly that the real potential for Ketamine to provide relief, especially for chronic pain patients, is when combined with psychotherapy. Psychotherapy allows the individual to process their experience and build off this experience to lead to new psychological frameworks for processing both internal and external stimuli.

Pain is complex, and Ketamine assisted psychotherapy is not one-size-fits-all. Our treatment plan gives patients with treatment-resistant chronic pain and even opiate dependance a chance to try a different and effective treatment.

Post Traumatic Stress Disorder (PTSD) is a major public health concern, affecting up to 7% of Americans.

As many as half of all Americans with PTSD get inadequate relief from traditional treatments which include antidepressants, antipsychotics, and cognitive behavioral therapy.

Ketamine combined with psychotherapy has been shown to be very effective at reducing the symptoms of PTSD. These effects last well beyond its near immediate relief.

Many mechanistic actions for how Ketamine works in PTSD have been proposed.

Ketamine allows people to reacquaint themselves with their past inciting trauma from an emotionally neutral perspective. Ketamine will not make you forget about the trauma. It can allow you to acknowledge its occurrence in a neutral way in order to not be continually re-traumatized by thinking about it.

Depending on the patient, outcomes can be noticed almost immediately with a sense of lightness and joy. Ketamine followed by psychotherapy has been shown to lead to significant relief of the burdens of PTSD.

Traditional treatments for anxiety will often either work poorly, have addictive properties, or severe side effects including brain fog and drowsiness. Furthermore, these treatments tend to have reduced efficacy over time, and lead to only transient relief of symptoms.

Ketamine, when combined with our novel integrative psychotherapy, can lead to significant relief of anxiety.

During the ketamine infusion and integration process, patients will often get a better understanding of their anxiety, and are able to reframe many of the triggers that often provoke their anxiety.

Ketamine has properties that allow for rewiring of the brain (new synapse formation and repair of existing synapses). Ketamine allows people to effect changes into their own lives. It shows people that they have the power to heal from within and take control of their relationship with anxiety.

Ketamine has been shown to be extremely effective and safe for patients with depression and treatment resistant depression (those who fail to get relief from two or more antidepressants).

Ketamine is highly effective at rapidly (within 2-8 hours) reducing depressive symptoms. Traditional antidepressants often take weeks to months to work.

Many traditional antidepressants have side effects including reduced libido, weight gain, GI upset, mood disturbances, and unfortunately require daily use for months to years.

Many antidepressants, even if they do work, require you to be on them for years, if not for the rest of your life.

Ketamine treatment has been shown in most patients to lead to resolution of symptoms without the need for any further medications.

Ketamine is not a medication meant to be taken for the rest of your life. The goal is to provide sustained relief after the completion of a set treatment plan. This is accomplished by combining the actions of Ketamine in the brain with psychotherapy. Additional enhancement sessions available as needed.

Unfortunately, there is a significant subset of patients that do not get significant relief from traditional cognitive behavioral therapy. Ketamine acts as a catalyst to stimulate a patient’s innate capacity for psychological healing. This allows patients to overcome past experiences and learned behavior to truly heal. Ketamine, combined with therapists who are specifically trained to work with psychedelic therapies, can lead to profound breakthroughs and deep psychological healing.
