Patient Comments (5)

He is amazing...I've been to him for 4 years. My life is better because of him. Hes caring, understanding, always open minded and I feel 100% comfortable. Ive seen 2 others who were awful, finally found a good one!

He's open-minded, accommodating and friendly - very easy to talk to. I've been a patient of his for four years now. My condition is chronic (no cure), but since seeing him, things have improved greatly.

The first psychiatrist I have dealt with who sincerely gives a rip about the struggle I personally have. I cannot thank him enough for having a professional approach yet maintaining the human level. His office staff is nice and encouraging, too. The wait time is always minimal.
