A trusted dermatologist for Lake St. Louis, Missouri

Lake St. Louis 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 individuals and families throughout Lake St. Louis, Wentzville, 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 Lake St. Louis families.

Common questions

FAQs for Lake St. Louis patients.

What if I’m not sure whether my concern is serious?

That’s exactly what we’re here for. If you’ve noticed a new rash, persistent acne, or a changing spot, we can evaluate it and determine whether treatment or monitoring is the right next step. You don’t need to arrive with a diagnosis.

How soon can I get an appointment?

Most new patients are seen within the same week. Availability varies by the type of visit, and our team works to schedule you as promptly as possible based on medical urgency and the location that’s most convenient for you.

When should I schedule a skin check?

If you have a history of significant sun exposure, changing moles, or a personal or family history of skin cancer, periodic skin exams may be recommended. We can help determine the right schedule for you at your visit.

What if I’ve seen another provider before?

That’s completely fine. Bring any prior records or pathology reports if you have them, and we’ll review your history as part of your evaluation.

Went there for MOHS surgery. Everyone there was very kind and helpful. Dr. Beal was very good with the surgery. If I ever have another need that they can help with they would be my first choice for care.
