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.

During a skin cancer screening, our dermatologists will perform a comprehensive examination of your skin to identify any suspicious lesions or changes. If necessary, we utilize Superficial Radiation Therapy (SRT) as a non-invasive treatment option for certain types of skin cancer.

Microneedling with PRP combines tiny skin-penetrating needles with platelet-rich plasma derived from your own blood. This treatment stimulates collagen production, improves skin texture, and reduces fine lines, scars, and hyperpigmentation.

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.
