 What our patients are saying:

“I'm a different person. I sleep better. Tons of energy, great outlook, I don’t know how I can be any better.”

“I feel the best I've been in a long time. Like myself. Havent taken any anxiety meds for 6 days, haven’t had the need. More focused, more productive, and less chaotic."

"I have worked with at least three different psychiatrists over the past 10 years, and feel so fortunate to have come to see Dr. Alex Dimitriu. Through his caring and knowledgeable approach, he has helped me do better than I have in many many years. He is a very informed and intelligent clinician with extensive knowledge of psychiatric medication. Beyond this, he is a very caring and compassionate doctor who goes above and beyond his clinical role. He has helped me tremendously, and I will forever be grateful."

"The first thing that struck me was his extreme compassion, concern and how he immediately made me feel at ease. He LISTENED to me and my story; it seemed that he took it almost personally and he immediately went to work on my behalf. Within 1 hour, Dr. Dimitriu had accomplished more than my doctors at home had in the last few years."

"He actually listens and works WITH you to come up with solutions. Unlike other doctors, he never blamed me and I felt like he was my partner (albeit a much smarter partner) at all times. I now sleep 7 or 8 hours every night. He's also a warm person, easy to talk to, no big ego and has a great sense of humor."
