Renew Ketamine Infusion — Ketamine Clinic in Seal Beach, CA

After therapy since 9, different medications since 15, and trying things like TMS and other treatments, at 21 I felt defeated. My depression was relentless and after a decade of struggling, I was referred to Renew. I was very nervous and skeptical at first. I had heard about ketamine-assisted therapies but felt fearful of the unknown and putting myself in such a vulnerable place. After my first call with Dr. Richter I was put at ease. Although still worried, I went through with the treatment. I was met with kindness and compassion from everyone there, a safe space, and highly-qualified clinicians helping me. Ketamine in conjunction with an integration therapist has given me relief I never thought was possible. I suddenly had been given a new capacity to feel emotions and lessen the dark cloud that followed me around for so long. I truly was skeptical at first because I have always been that person that treatment seems to not work on. Ketamine, however, has become a lifeline. Though I do give a lot of credit to the medication itself, Renew and Dr. Richter and Dr. Doshi have really been the ones who have made this experience so impactful. I cannot recommend this place enough if you struggle with depression and/or trauma. Relief is possible through Renew.

After years of treating my depression with common prescriptions, I have had the most profound experience from Ketamine treatment. At first I was discouraged because I didn't know this to be an alternative treatment. I was scared of all my emotions coming forward at once after years of feeling blunted and constricted by the anti-depressants. But the set and setting make such a difference as well as provider support. Dr David Richter presents with tremendous compassion, insight, safety, and attunement. He see's you as a whole person, he welcomes curiosity every step of the way, and very patient and kind towards your process. I feel lucky to be a part of such a movement where we can address mental health from a comprehensive and introspective approach such as this.

After giving it much thought and research, I was hesitant but hopeful when I decided to try ketamine treatment. I can honestly say it has been life-changing. Dr. Richter and his team @ Renew Ketamine Infusion provides a safe, confidential and relaxing environment. Within a few sessions, I began to feel lighter, more present, and more engaged in my relationship with self and others. The team made me feel safe, informed, and supported every step of the way. The experience has given me a sense of peace and clarity. This approach to healing and wellness adds depth and context to traditional talk therapy. I highly recommend Renew Ketamine Infusion as their whole-person care and service sets the standard.

I cannot say enough about Dr. Richter and his incredible team. From the very first consultation, I felt truly seen, heard, and supported in a way I never had before. I’ve struggled with mental health for most of my life, and after trying what felt like every option out there, ketamine therapy with Dr. Richter was the breakthrough I didn’t know was possible. The care, compassion, and professionalism of this entire office is unmatched. They created a space where I felt completely safe and respected — and that made all the difference. Throughout my sessions, I experienced a few deep, life-changing breakthroughs that shifted something inside me. I’m now able to show up in my life with more lightness, clarity, and genuine happiness. I am finally starting to feel like myself — or maybe discovering who I truly am for the first time — and it’s because of this treatment and the people behind it. If you’re on the fence or feel like nothing has worked, please know there is hope, and it might just start here. Thank you, Dr. Richter and staff, for helping me reconnect with life in a meaningful, lasting way. You have truly changed my life. — LMT

If you’re curious about Spravato or therapeutic ketamine in general, I highly recommend checking out Renew, Dr. David Richter’s clinic. I went in for Spravato, the nasal spray version of ketamine, and found it to be extremely effective, much less intimidating than IV treatments, and easy to incorporate into my routine. One of my biggest concerns going in was dealing with insurance and enrollment—I assumed it would be a frustrating maze of paperwork. But the team at Renew made the whole process incredibly smooth and stress-free. They took care of the logistics, explained everything clearly, and made sure there were no surprises. The clinic itself is serene, located in a peaceful area that sets the tone right away. The treatment room is especially impressive—quiet, thoughtfully designed, and calming. It doesn’t feel like a doctor’s office at all. And then there’s Dr. David Richter, who’s easily one of the most engaged and generous doctors I’ve ever met. He takes his time with you—not just to go over logistics, but to really talk through what to expect, how you’re doing, and what comes next. He doesn’t rush, doesn’t delegate the important stuff, and is genuinely present throughout the process. What stood out to me most was how personally involved he is—not only during the sessions but afterwards too. He personally followed up the day after each treatment to check in, answer questions, and make sure everything was on track. That kind of follow-through is rare and meant a lot. He’s clearly a skilled physician, but what makes him stand out is that he’s also an incredibly thoughtful and informed therapist. You don’t just feel like you’re getting a treatment—you feel like someone is actually guiding you through a process with care and insight. If you’re just exploring ketamine as an option, I’d definitely recommend talking to Dr. Richter. He’s not pushy at all—in fact, he’s probably the least “salesy” medical professional I’ve ever met. He’ll walk you through the pros and cons with complete honesty, and he’s happy to answer questions without trying to steer you one way or another. From the calm, welcoming environment to the thoughtful care and top-notch professionalism, I couldn’t have asked for a better experience. If you’re considering Spravato or just want to learn more about what the process is like, this is a great place to start.

This ketamine treatment is the absolute best I personally have ever done. I have done ketamine since 2022 which released me from the worst depression of my lifetime. I took a break for a while & found Dr. Richter’s practice to be the most incredible four sessions I’ve ever experienced. This treatment has many facets to making it all come together & Dr. Richter has this tuned to perfection. Try this practice just once & you will have found your home with ketamine treatments

I am so grateful for this experience and would highly recommend this clinic to anyone considering this path to healing! I was initially hesitant about starting ketamine therapy, but Dr. Richter and his incredible team transformed it into a truly life-changing journey. From the very beginning, they were supportive, compassionate, and exceptionally knowledgeable. Their care created a safe space that allowed me to heal from within unlike any other therapy I have tried before. Thank you!

I am in a very demanding career and being experiencing signs of depression A friend recommended me Ketamine infusion, I was open to try and see if will help me coping with stress, anxiety and depression. I try a clinic in New Port beach but the experience was very poor. I contacted Dr. David Richer and scheduled another session and that was a life changing experience for me, him and stuff provided a warm very safe welcoming experience. Do to his knowledge and guidance I had a break though experience. No only felt relief my previous conditions but begins to get better. I can only say that thanks to him I had a different perspective on life and begin to improve.
