Many of our patients see results in the first several sessions. It is very rewarding for me, personally, to see people finally get better after suffering for so many years.

Dr. Simelgor

Thank you so much – not only for helping me finally feel like a person again, but for always treating me with empathy, care and respect.


I had my first ketamine therapy session last week, and it was amazing – it simply turned the darker elements of the depression off like a light switch!


“…Melinda (medical coordinator) was very personable, easy to talk to and efficient. I felt like she really listened, appreciated me as a person and as a patient…”

Courtney P.

“I was very happy and impressed with Dr. Simelgor and his staff. They were thorough and professional”

Brian L

“The staff was great from the start. Everyone was so nice. I had a tough medical year, and it was especially reassuring when Eric (nurse practitioner) paused and said ‘we are going to take good care of you.’ Thank you for your kindness and care.”
