Allyson was truly a class act. Seeing a new psychiatrist can feel nerve-wracking and she completely put me at east. Spent a significant amount of the appointment getting to know me and the reason for my visit and having a very exploratory conversation to be sure to recommend the appropriate care. I feel very seen and very understood! Would highly recommend

I had initially booked with another provider but they were unavailable so the practice moved my appointment to Dr. Cosgrove, who was very attentive, professional, and a great fit for me. I have already booked a follow up appointment and am looking forward to speaking with her again.

I had a seamless and pleasant experience with Allyson Cosgrove. Allyson is a gentle speaker and an excellent listener, making me feel comfortable throughout our consultation. Even though it was my first time visiting a psychiatrist, her open-minded approach made it easy for me to discuss all of my concerns. What stood out the most was how extremely helpful she was in offering clear advice and thoughtful solutions, while also explaining the purpose of the medication and how it could help. The virtual visit was seamless, thanks to a user-friendly online portal. The staff was incredibly helpful in setting up the appointment to accommodate my schedule. Overall, I’m very pleased with the care and convenience provided. - Fahim

Was not the Dr I originally booked. They called me to say they were double booked and passed me onto someone else. Was prescribed a medication that still hasn’t been called in. Would not recommend. Was also late to the appt I had to call the practice to make sure someone was showing up.
