I came to this professional to seek an evaluation for ADHD and possible medication. We were well into our session before I was told he could not prescribe medication, but I continued with the session.
I have since found a Psychiatrist who evaluated me for ADHD and has prescribed medication. I mistakenly made an appointment with the wrong type of medical professional.

We only had one session for couples therapy, but he was able to see our issues with clarity and offer an optimistic pathway out of our loops.

Dr. Pasagiannis was very attentive and fair. We came for couple’s counseling and he made sure everyone had the opportunity to respond and share how they were feeling. His background in multiple specialty areas really gave us the opportunity to look at our complex issues.

Dr. Pasagiannis responded to my needs in a warm and inviting manner, asking timely questions that helped clarify factors contributing to my anxiety while providing me with tools to decrease the stress I was experiencing. He is approachable, kind, and authentic. Highly recommended.

Dr. John is an exceptional therapist with a broad ranging skill set. He is affable, emapthetic and effective. Our time together has assisted me in achieving a range of personal goals. As an openly gay man, it can be more challening to find a professional with an apprectiation for some of the unique challenges in the lives of LGBT individuals. I highly reccomend Dr. John and belive he can be of assistance to a diverse set of patients and needs.

Dr. Pasagiannis is a warm, caring therapist. He is insightful and able to provide feedback in a clear, concise manner that was useful and helped me work through some issues that were causing me distress. He was also able to offer stress management tools that I could use to manage difficult periods at work. Highly recommended.

I've been seeing John for over two years. He's exceedingly professional, easy to work with, and knows when to listen, when to talk, and what questions to ask. When we are together, it truly feels we are collaborators working towards a common goal.
I know that choosing a therapist is a deeply personal decision and that different people look for different things, so I can only share my own experience. Over the past two and a half years, my life has gotten better: my anxiety has gotten easier to deal with, I have become more like the person I want to be both at work and in my personal life, and I am happier. I attribute this primarily to my work with John. I would not hesitate to recommend him to anyone.
