Absolutely wonderful practice I would give 20 ⭐ EVERYONE is amazing, very friendly, welcoming and compassionate! HIGHLY RECOMMEND TO EVERYONE THAT IS LOOKING FOR A CARING, COMPASSIONATE DERMATOLOGIST. Thank you Debbie Ruiz
Response from the owner:Thank you so much for taking the time to update your review, Debbie. We're grateful that our quick response and follow-up call demonstrated how seriously we take patient feedback. It means everything to us that you've decided to stay as a patient after our conversation. We sincerely apologize for the unfriendly and unwelcoming experience you had with our front desk receptionist. As a former RN with 20 years of experience, you absolutely know what proper patient care should look like, and we failed to meet those standards. Your discomfort and feeling unwelcome is completely unacceptable. We're pleased that our PA and MA provided the wonderful care you deserved, but we understand that the front desk experience significantly impacted your visit. Thank you for giving us the opportunity to address this matter and for your patience as we work to ensure all our patients feel welcomed from the moment they arrive. We truly appreciate your loyalty to our practice and your constructive feedback. -RFSA Dermatology Team

Dr R. was quick, thorough, attentive, and courteous. The entire appointment from when I arrived to when I left took less than 20 minutes, but I still felt he gave a very full exam, calling out everything he saw as he went over me. The nurse had my prescription called in before the doctor even finished. Absolutely 5 stars.
Response from the owner:We’re glad Dr. R. gave you a quick, thorough visit without making it feel rushed. “Quick” and “very full exam” is exactly the balance we aim for, and it’s great to hear the nurse had your prescription called in so promptly. We appreciate you sharing this.

My first time ever being seen by a Dermatologist and had a great experience in doing so. Staff was great and so was Dr Rainey. I had 3 concerns and unexpectedly attended to them within the same visit. Dr Christy Rainey is awesome and has great bedside manners. I will be scheduling my mother for some services that she’d love to get here soon.
Response from the owner:Three concerns handled in one visit is exactly the kind of care we hope for. We’re glad Dr. Christy Rainey and the staff made your first dermatology appointment feel easy and thorough, and it’s wonderful to hear you’d trust us with your mother too.

I first came to Dr. Rainey to seek help with a cyst I’ve had for a few years now and he has absolutely gone above and beyond in his services. He took care of the cyst and put me on a skin routine that has made a huge improvement on my face and skin. I’m incredibly grateful to have ended up in Dr Rainey’s care.
Response from the owner:Helping with a cyst that’s been bothering you for years and then seeing your skin routine make a real difference is exactly the kind of progress we hope for. We’re so glad Dr. Rainey could be part of that turnaround and that your skin is feeling better too.
