My treatment of TMS was more beneficial than I anticipated. There was more than one overall positive improvement – lower frustration and stress / an increase positive outlook on life / better reaction control with life situations / and overall feeling better about myself and my environment. Between the actual treatment and the mini talking sessions with mark it was a powerful combo to improve my mental state. The medical devices worked extremely well with zero pain & the talking sessions provided in a way a mini therapy session. Overall I would say this was the best choice I’ve made for myself in a long time.

I recently underwent a series of TMS sessions, and I can confidently say that it has been a game-changer for me. As the sessions progressed, I noticed a significant improvement in my symptoms. I am grateful to have found this treatment and would highly recommend it to anyone seeking an alternative to traditional therapies.
Layla C
Such a great experience with Dr. TMS Therapy. The front desk and clinical staff are thorough, patient, and very friendly. I would recommend this practice to anyone who is interested in an alternative or companion to traditional mental health medicine.

I was hopeful but skeptical about this process but the team at Dr. TMS Therapy Griffith Psychiatry were very helpful in making sure I understood the process and was comfortable. They dealt with my insurance company and really made this an easy process. Mark administered my treatment and he is not only knowledgeable but understanding and super encouraging during a very vulnerable time. I feel a lot better and more in control of my depression and I am so grateful for my experience.

Nancy L
Great staff, and happy I was a patient of TMS. Well worth every bit of it. Personally, I have felt lousy, depressed and all of the above for so long I really did not believe things would change. It was very around the 3rd week I felt like my emotions were back after many, many years of feeling emotionless. I was looking forward to things again. I’m here to say TMS is the best therapy I could have ask for. Oh so, definitely worth it! Also the staff were kind and very supportive. Just do it and commit. Again, well worth it!
Hunter Russ
Dr. Griffith and his team are some of the most excellent clinicians I’ve had the pleasure of being treated by. Everyone in the office was kind and understanding and they took the time to answer all of my questions when I was initially nervous about the treatment process. My technician Mark went above and beyond to make sure I was given the best care possible. I highly recommend Dr. Griffith’s office if you are looking for TMS treatment.
TMS has been a lifesaver! Twenty plus years on medication and I am now pill free! Didn’t think it was possible but TMS really works. Dr. Griffith and staff are wonderful and his office is relaxing and soothing.
