As always, thank you Dr Bahnassi! Its been 9 years of treatment with Dr. B and I am very lucky to have someone so bright, speaking of psychiatric treatment as well as treating me! I admit that somedays I don't know which way Show moreis up, and I am a handful-but he truly cares about us as people, not just another messed up mind. To anyone lucky enough to given Dr. Bahnassi as your physician, just trust in him. Report all feelings, good&bad-and let him help you get better!

I'm Dr.Bs patient roughly 8yrs. Im a handful. I can't not talk 1M miles/min. I aggravate nearly everyone that doesn't know about my illnesses upon meeting. Dr.B has fought to care for me not just that month, he's Show moreconcerned about me at 75 y/o. I trust him even the times of distress. They don't make Physician's like Doc Bahnassi. He is the Unicorn! Dr. B YOU'RE THE GOAT! THANK YOU KINDLY. Jennifer Gervais

About Mohamad Bahnassi, MD

Amjad Bahnassi quite literally could not have gotten out of Syria any sooner. Born and raised in the capital of Damascus, Bahnassi graduated high school at 16 and finished medical school at 22. The day after graduation, he left. "I was ready," he said. Bahnassi came to Worcester in the early 1980s for a residency program at UMass Medical Center as a psychiatrist and never left. After completing his residency, he started Behavioral Healthcare Services, a practice he still leads after more than 25 years.​

I had a cordial and productive visit. The doctor and I discussed my current medications and the conclusion was that they are working very well for me and there would be no reason to adjust dosages or change any medication. I feel that a review like this is important and also reassuring .

Charles L • July 07, 2026

Dr Bahnassi is the best psychiatrist and psychopharmacologist in the state!! He really knows his meds!!! I can’t imagine going to anyone else!! At behavioral health care services I see DrB on the first floor, therapy on the second floor and Genoa pharmacy on the 3rd floor!! I would never go to any other clinic!! Very close to home too!!
