A trusted dermatologist for Warrenton, Missouri

Warrenton and Warren County residents don’t have to settle for limited local options or drive into the city for specialist-level skin care — our Troy office is an easy drive northeast, bringing medical dermatology, cosmetic surgery, and advanced laser treatment within reach. We’re glad to welcome patients from Warrenton, Wright City, and the surrounding communities.

As a locally owned, medically directed practice, we prioritize personalized treatment plans over one-size-fits-all protocols. Whether you’re booking a routine skin exam, treating acne, or considering cosmetic surgery, care comes from Dr. Brandon T. Beal and our exceptional team — never a corporate chain. Most new patients are seen within the same week, and we accept Medicare and most major insurance for medical visits.

Find us at 520 E Cherry Street, Troy, MO 63379, or call (314) 834-1400. We also welcome patients at our second location in Chesterfield.

Response from the owner:Your feedback is highly appreciated. Thank you for the review!
Very nice people. When I made an appointment online and the computer had a glitch and signed me up for a different location than what I chose, I showed them the confirmation on my phone from the Troy location, which is where I wanted to go, but on their end it showed another location. So they found time to see me since I had already taken off work early for the day. That’s how customer service works. I appreciate it. Not easy to keep taking off work to go to appointments.
Response from the owner:We appreciate the kind words and are glad we could provide you with a positive experience!

Love this office! Always on time and everyone is so nice. Jennifer Swofford PA is awesome. Highly recommend. I love being able to go to Troy Mo for quality care instead of dealing with the hassle of driving to St. Louis and all the traffic.
