Regina Tengler @ RFSA Dermatology Castle Hills, I had an excellent experience at A Dermatology in Castle Hills. I was first seen by Regina Tangler, FNP-C. Dr. Christie Rainey, MD, then came in to provide her opinion, and Felicity, the medical assistant, was also wonderful. The entire team was absolutely great. From the moment I arrived to the front desk it was great , they took the time to thoroughly explain what was going on and answer all of my questions in a way that was clear, reassuring, and easy to understand. They created such a friendly and comfortable environment and helped ease any anxiety I had without making me feel unnecessarily worried or alarmed. Dr. Rainey was extremely knowledgeable and professional. I was very impressed with her knowledge and with how thoroughly she explained everything we discussed that day. She made sure I understood what was going on and took the time to address my concerns. Regina and Felicity was wonderful. They were kind, knowledgeable, professional, and made the entire experience feel comfortable and reassuring from beginning to end. The entire team worked so well together and provided excellent care. Their professionalism, kindness, knowledge, and ability to make patients feel at ease really stood out to me. I truly appreciate the care I received and would absolutely recommend Dr. Christie Rainey, Regina Tangler, Felicity, and the entire team at A Dermatology in Castle Hills. Definitely a five-star experience!
