My time with Cambridge TMS was an amazing experience, so I hope this review gets others interested.Cambridge TMS knows a positive attitude goes a long way toward helping you reach your goals, so they make every interaction a chance to lift their patients' spirits by providing exceptional medical care in a fun, friendly environment. During the intake, CJ answered my many questions about TMS and juggled the scheduling of all my appointments. Isabel greeted me each morning and, if I had to complete a questionnaire, remembered my birthday to log me into their patient portal so I could easily get started. Daniel was so precise with the treatments and provided Bluetooth speakers to listen to podcasts while they were happening. As a side note, we both listened to Smartless through the week, and now that treatments are over, I'm missing his company! Dr. Brenner checks in now and then to make sure everything is humming along, which it always is, of course.They are the gold standard in medical care. From my first appointment to my last, they made me feel like the only patient and that my care was of the utmost importance. As a result, I'm smiling now as I go back to my normal life.

I am so thankful that I found Cambridge Biotherapies. Each and every staff person here - from the first time you reach out throughout your clinical experiences - is caring, supportive, and informative. When I went for treatment, I felt safe and cared-for throughout. It is nice to feel like a person, not a patient.Update: I have completed my initial treatment series of Ketamine. What a difference! I have had a tremendous improvement in my depression and have started a maintenance regime. Staff continue to work collaboratively with me and - without exception - display intelligence, warmth, and kindness. If you are struggling, please consider treatment here. It has made a world of difference for me.

After trying everything else for twenty years, and finding nothing worked, I found Cambridge Bio therapies. I have done both TMS and Ketamine infusion with very good results. There is hope here and it does get better. So if you are depressed or having PTSD, or both...you should try this.

What can I say...this place changed my life. Their dedicated & compassionate staff assisted me in breaking free from my depression that I've been dealing with my whole life. They follow the up-to-date science and work one-on-one with you to adapt & customize your treatment plan. I did both TMS & Ketamine and was responsive to both, but everyone is different. I would highly recommend anyone who has struggled with depression for a long time to schedule an initial appointment, this might just be the breakthrough you need when you've already tried everything else.

I can't recommend Cambridge Biotherapies highly enough. Everyone who works here is highly competent and a pleasure to interact with.

I’m set to begin the SAINT (Stanford) TMS Protocol and am super excited.I’ve had a video meeting with Dr. Brenner, who i thought was awesome and also very bright and friendly. Also CJ Comeau, who has helped my schedule appointments and answer all my questions is super nice and professional. The case worker (Sarah I believe) who interviewed me before I met with Dr. Brenner was also super friendly.So while I cannot speak to or provide any rating/review or comment as to how the SAINT TMS Protocol was for me, I can say all interactions with everyone at Cambridge Biotherapies has been awesome.Lastly, I just want to note how important the research and work that places like Cambridge Biotherapies are doing to advance mental health care. Ketamine, Theta Bursts, and TMS are in my opinion going to be part of the way of the future (perhaps with the addition of the novel use of other psychedelic compounds like Psilocybin, MDMA, LSD, etc once the building research can further establish their benefits for a variety of ailments).
