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.

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.

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.

SRT is a non-invasive treatment for certain types of skin cancer and keloids. It uses low-dose radiation to target and treat affected areas without surgery.

Botox treatments are minimally invasive and typically well-tolerated. The procedure involves small injections, and we use techniques to ensure your comfort throughout the process.

After a laser hair removal session, you may experience mild redness or sensitivity, which typically resolves quickly. For optimal results, multiple sessions are recommended.

We recommend annual skin cancer screenings or more frequent visits if you have a history of skin cancer or other risk factors. Early detection is key to effective treatment.
