“I had a really great experience. He actually listened and asked thoughtful questions that felt like they had a purpose, not just checking boxes. I felt calm, heard, and comfortable opening up, which doesn’t always happen for me.
What stood out most was how knowledgeable he was. He clearly knows what he’s doing and even looked into things for me further. When I had trouble explaining something, he helped guide me and put my thoughts into words without making me feel rushed or judged.
Overall, I felt supported and understood. I’d definitely go back.”

Incredibly friendly and transparent, asked good questions - did not ask questions just to ask questions.

Absolutely horrible experience. I was ghosted for my appointment despite the sensitive nature of the visit. I had already moved my schedule around and even agreed to the provider’s initial request to reschedule, only for them to not show up at all. I waited the entire hour with no heads-up. When I called the office, they promised a callback that didn’t come until four hours later. The lack of communication and accountability is incredibly shady. Save your time and find a legitimate practice elsewhere

Very thorough and easy going. Kind and not pushy. Went through entire mental health history in an hour and was a good listener. Would definitely recommend to someone worried about seeking mental health care.
March 5, 2026Shea G.Verified patientVideo visit
Gregory was wonderful and really took the time to listen to what I had to say. He didn’t try to rush our appointment and took the time to discuss options and gave a detailed approach to my needs. I would highly recommend him to anyone.

Greg is very attentive, and clear in his recommendations and care plan options. He takes time to explain everything and does not rush you during the appointment. He makes sure to answer any questions you may have and avoids repetitive questions during intake. He made the environment very comfortable to explain the issues I was experiencing. I will definitely be making my future appointments with Greg!
