“When researching psychiatrists I have a number of qualities I look for. Dr. D’Agostino exceeded all of them. He is patient, caring, incredibly brilliant and most importantly really listens to his patients. I’ve learned so much from him and I’m incredibly grateful.”

“I could not recommend Dr. Mark D’Agostino more! I had the pleasure of working closely with Dr. D’Agostino as colleague at Silver Hill Hospital. On a personal level, Dr. D’Agostino treated a family member of mine and I could not have been more grateful! His comforting words, active listening skills, and presence with his patients cannot be matched. His brilliance in the field of psychiatry shows through with every life he touches.”

“Mark was one of the best psychiatrists I've worked with! Unfortunately for us, he has moved on to private practice, (and lucky for others). He is extremely intelligent, though I believe that is not the only aspect of a psychiatrist that illustrates greatness. I value his personable nature, sense of humor, quick wit, as well as his ability to create unique relationships based on true empathy. He is able to make work not seem like a job. He loves what he does, and that shines through to patients and staff... even on the more challenging days!"

“I worked with Dr. D in the IOP at Silver Hill. He's the best! He explained things, and always took time with me. I'll miss working with him.”
