"I've been seeing Dr. Q for years and she's made such a huge impact on my mental health. Being able to do talk therapy and medication with the same provider has been a game changer and I've made so much progress. She understands what I need from therapy and has a lot of good ideas. I have been in therapy on and off for over a decade, and some therapists make me feel like I have already heard it all. But with Dr. Quimson I look forward to our visits and always come away feeling more centered. She has uncovered some diagnosis that other doctors missed and is now helping me treat issues that I didn't even realize were impacting me so much. She is compassionate and understanding, but challenges me when I need it, which I appreciate. I've tried different medications under her care, but never felt pressure to explore an option I wasn't interested in - she never suggests a medication unless we talk through the situation and other options first. Her colleague Jamie who does scheduling is also very easy to work with. You can reach out to them via text messaging, which makes it so much easier for me to reschedule appointments and get refills. Overall, Dr. Quimson has made a huge impact on my life because she provides high quality care, and it is a bonus that her office is very easy to work with."
"This was my first time working with a psychiatrist, and I have been more than satisfied. Dr. Quimson-Guevarra is responsive and takes the time to understand your individual situation. I appreciate regular check-ins and easy ways to reach out when needed. I definitely would recommend!"
