CLIENTS
KELLY
Dr. Sylvester is an amazing Dr. I've tried seeing other Drs. and therapists in the past which made me feel like a number and not an actual person. Thankfully right before I was about to give up in finding help I found Dr.Sylvester. He's extremely knowledgeable, compassionate and he thinks outside the box. I would highly recommend him.
CHRISTOPHER

LAURA

DAVID
Dr. Sylvester is best! I have been a patient for nearly a decade. I used to be crazy and now I'm not. In all seriousness though, Dr. Sylvester is compassionate, understanding, and one of the most intelligent individuals that I have ever met. I have the upmost respect his opinion and would recommend him to anyone struggling with addiction . He gets it! He succeeded with me where others have failed. 11 stars out of 10

Dr. Sylvester is one of the best Doctor’s I’ve ever had the pleasure of being treated by. He’s a true professional, and highly knowledgeable, with nothing but the patients best needs in mind. I trust him immensely and would recommend him to anyone looking for high quality care.
MARY
I’ve been a patient of Dr. Sylvester for over 10 years!!! I really can’t believe how time flies. Doctor Sylvester has always been easy to talk to and supportive . Although I used to see him in person, the last few years has been through Telemedicine. I love the convenience of telemedicine. Especially now with the Coronavirus. It’s just so much easier.

Dr.Sylvester is seriously the best psychiatrist. I was a little apprehensive at first because I’m use to falling through the cracks and always leave feeling defeated and getting no help. Dr.Sylvester was genuine, kind and just down to earth . He made me feel like I mattered my life mattered. He continues to help me reach my goals while making me stronger in the process. I highly recommend Dr.Sylvester if you want results .
