Galler Rimm Behavioral Health
Psychiatry, Developmental, and Behavioral Health for children, adults, families and couples. Sign up for the Galler Rimm newsletter to learn more about Personalized Repetitive Transcranial Magnetic Stimulation and our other services. I'm happy to say it's been 10 years since becoming a patient of Dr. Rimm.

My other doctor had me on about 10 medications and I am now only on 3! Can you imagine how my life was being on so many medications at once for so long? I have so much respect for Dr. Rimm. I now smile and have more laughter than I did previous to seeing him. He has helped me. Many of us well-intended parents find ourselves overwhelmed and full of self-doubt about our roles in our children's lives.

Dr. Rimm has been my therapist for many years. I had several other therapists before I began treatment with him. But it has been his methods that have improved my life, helping me to understand and heal my trauma. He doesn't candy-coat things or necessarily "hold my hand." But he helps me to see myself for who I am (when I couldn't) and to see and build upon my strengths. He helped me to understand and overcome the family dynamics that propelled me to some seriously dark places. He is very community-driven, teaching that we can't get better by ourselves. I had to

My son is 11 yrs old and have seen Dr Gabrielle for his autism and ADHD a couple times just before the pandemic hit. Recently I been trying to get him an appointment to see her again, especially because we were in the process of getting him an ABA. We never got to that point due to the pandemic. So I tried to get him in since he has been suicidal. They turned him away, saying they were full and not taking new patients. Ummm he was already a patient. In My situation I would expect them to find time for him. Her assistant, Jessica was really rude saying "Don't you understand what full means?" yes

There are many similarities in previous postings and had I reviewed them my time with Dr Rimm would have ended much sooner.
Oh my! He does love to share with you his accomplishments and the technique's he's learned over the years and then your session is over. After my session's I would go over what Dr Rimm discussed we me. I was amazed others shared the same thoughts. It's more a Dr Rimm me session. He gets paid and his clients/patient's get to make another appointment to listen to Dr Rimm talk about his knowledge and his success.
During one of my session's I had to ask him to quit talking.

Purposefully mean and vindictive! I’m so appalled at what my daughter is telling me about her therapy sessions. She’s been crying all afternoon. I’ll never allow her to go back. Don’t let your children go to therapy alone!

It has been my experience that Dr. Gabi is kind, extremely professional, and genuinely committed to her practice. It is wildly difficult to find a health care provider who is interested in their patients as people, rather than just numbers and letters on a chart. Dr. Gabi is one of these people.

This is the worst practice I've ever dealt with. My heart breaks for the people they are "helping". They seem nice and flexible at first but will soon demand unrealistic results. Nasty superiority complex, unprofessional, controlling...I can't think of anything nice to say about them

After a few years of trying to deal with the condescending attitude, comments, contradicting information and eye rolls, I finally tried to see if I could be prescribed the medicine my son NEEDS without all the added drama. The response: a certified letter telling me that Dr. Gabby "will no longer be able to serve as your son's physician". As relieved as I am that I won't have that issue in my life, I do feel it is wrong for a doctor to put a family in need into this position. Now to search and find a doctor that can prescribe for my son who is both in our location and takes
