We had such a positive experience at oak tree for my daughter’s first-ever dermatology appointment. From the moment we walked in, the staff was friendly, professional, and made her feel completely at ease. Dr. Ally was incrediblyShow more kind, patient, and thorough. They took the time to explain everything in a way that my daughter (and I) could understand, and made sure. We had a wonderful experience!

I had a great experience with Ally, PA-C. She was knowledgeable, professional, and made me feel comfortable right away. She took the time to listen, answer my questions, and explain things clearly. The staff was also friendly and Show moreaccommodating. I called around noon and they were kind enough to squeeze me in for a 3:45 appointment. I really appreciated the care and flexibility. Highly recommend!

was greeted kindly at the front desk, and the staff made me feel welcome right away. When I was shown to the patient room, I was even offered coffee, which was such a thoughtful gesture. The ambience felt more like a spa than a clinic. Overall, I felt treated with kindness and respect, and I truly appreciate the care I received.✨

I’ve seen multiple dermatologists, on all those occasions I left feeling like they didn’t care or gave me zero confidence in them helping me. I’ve seen Alexandria twice and each time I feel like she actually cares, and really wants to help me.
