A trusted dermatologist for O’Fallon, Missouri

O’Fallon and St. Charles County residents have specialist-level skin care close to home. Our Chesterfield location puts medical dermatology, cosmetic surgery, and advanced laser treatment within an easy drive, and our original Troy office continues to serve the wider region. We care for busy families and professionals from O’Fallon, Lake St. Louis, 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.

Call (314) 834-1400 or request an appointment online. With two Missouri locations — Troy and Chesterfield — we make specialist care convenient for O’Fallon families.

Common questions

FAQs for O’Fallon patients.

What kinds of concerns should I come in for?

If something on your skin is bothering you — persistent, painful, changing, or simply uncertain — it’s reasonable to have it checked. We can evaluate it and guide you on the next steps, whether that’s treatment, monitoring, or reassurance.

What if I’m coming for a second opinion?

Second opinions are welcome. If you have prior records, biopsy results, or photos, bring them along and we’ll incorporate that information into your visit.

How should I prepare for my appointment?

Bring your ID, insurance card (if applicable), a list of your medications, and any relevant history. If you’re concerned about a specific area, note when it started and any changes you’ve observed.

Do you accept insurance?

We accept Medicare and work with many major insurance plans for medical dermatology. Coverage varies, so the best next step is to call — our team can help verify your specific plan details. Cosmetic procedures are typically self-pay.

Great overall experience with Dr. Beal and his staff! Dr. Beal is an excellent listener, thoroughly explains any questions and makes sure I understand the plan. I never feel rushed or pressured! Dr Beal has excellent bedside manner, concerned about how I’m tolerating the procedure. I am very happy with the results! I would highly recommend Dr Beal and his office, very professional!

They really know what they are doing and I have been treated very well. They are great about explaining things when I ask a question or accommodating me if I need to add an area to be looked at to my visit at the last minute. I will continue visiting this dermatologist office.

Very knowledgeable. Spent time explaining and listening to my questions. Gave me multiple options. Highly recommend.
Response from the owner:Thank you so much for leaving us a stellar review!
Wonderful experience! As a 1st time client, I was able to get in the same day. The front desk ladies were very kind and helpful. The nurse and nurse practitioner who assisted me were quick, informative, and incredibly nice. Luckily my condition wasn't anything of worry, but had it been, I believe I would've been taken care of.
