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.
