The experience was excellent. The office reached out and was efficient in setting up the appointment. The physician was amazing! He listened carefully and asked thoughtful questions. I lost my brother and wasn’t sure if seeing someone would help. I wasn’t sure if I should seek care but am glad I did! I highly recommend this provider! He listened, understood my needs, suggested a treatment plan to address my concerns, and make follow-up plans. I’m so glad I kept the appointment and look forward to seeing him again! I highly recommend this provider!

I recently had an appointment with Dr. Sebastian, and I couldn't be happier with my experience. From the moment the conversation started, Dr. Sebastian made me feel comfortable and at ease. He was kind, compassionate, and took the time to listen to all of my concerns. As someone who has struggled with mental health issues for years, finding a doctor who truly cares can be a challenge, but Dr. Smith exceeded my expectations. What I appreciated most about my visit was how thorough Dr. Sebastian was his evaluation. They asked detailed questions and took the time to understand my unique situation, which made me feel like he truly wanted to help me. In the end, Dr. Sebastian recommended a treatment plan that made sense for me, including medication and therapy options. Overall, I highly recommend Dr. Sebastian to anyone looking for a compassionate, caring, and knowledgeable psychiatrist.
