I have been seeing Dr. Finklea for over 16 months now and she is a breath of fresh air and model doctor in San Antonio. I trust her with my medical needs and appreciate her empathy, responsiveness, and high caliber patient skills and competency. She has completely changed and improved my quality of life and I am forever grateful. Also, short wait times is another benefit. Highly recommend her and the team at RFSA.

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.

Dr Finklea has been our dermatologist for 7 years. In that time she has taken care of several skin issues that we've had. She is very professional and helpful in explaining our skin problems and also in recommending what the next course of action should be. I highly recommend her as a dermatologist.

Dr Rainey and her entire staff are absolutely incredible. Let me start by saying, as a general rule I absolutely detest going to the doctor! However, this visit was a real game changer. Everyone I met on the staff were so warm, welcoming, and professional that I immediately felt at ease. After all of the preliminary stuff was done, I had the privilege of meeting Dr Rainey. All I can say is “Wow!”. Dr Rainey spent time getting to know me, addressed my concerns, and took the time to explain everything in simple to understand terms. Nothing about my visit felt hurried. For the first time in my life, I am already looking forward to an annual follow up visit with Dr Rainey next year. The rating scale only goes to 5 but honestly Dr Rainey and her entire practice deserve a 10++++.
Response from the owner:We love hearing this! Thank you for taking the time to leave us such a kind review. We’re thrilled to hear that you had a wonderful experience with Dr. Rainey and our team. It is always a pleasure serving you at RFSA Dermatology! –RFSA Dermatology Team

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.
