After my first visit with Charles, I’m convinced he is professional and going to help me with my needs. He LISTENED, asked important questions and immediately made the right changes to my prescription medications. I will meet him in person for our next appointment in his office. I felt seen and heard and that he has my mental care as his priority. Everything we discussed has been followed through, even my medical work accommodations at work. I needed that reassurance and look forward to his professional care. I feel comfortable with sharing my condition and expectations. I would recommend.

I’ve had the privilege of seeing Charles for a number of years. I can’t recommend him highly enough. He is kind, caring, and empathetic. Charles has created a safe and welcoming space where I feel truly heard and understood. Even when he gently challenges me to change or try something new, he does so with thoughtfulness and care. His approach never feels pushy—just encouraging and supportive, which makes it easier to take those important steps forward. I’m grateful for the support and guidance he continues to offer.

Charles created a warm, inviting atmosphere that has become my safe space. I feel comfortable being vulnerable and allowing him to see that vulnerability. I am completely honest with Charles because I trust his recommendations and appreciate his welcomed feedback. I am seen. Heard. Understood. Believed. I’d never had that before. This place is positively phenomenal, and I strongly recommend the facility for psychiatric treatment.
