One practice.
Five reasons people come in.
Each row shows what we do, how it’s usually paid for and how long it takes. A starting point for your first visit, not a diagnosis.
A mole that bleeds, itches or changes quickly should be seen within days. Call and tell us; we keep same-week slots for it.

Exam room, the first five minutes
Thirty minutes,
every inch.
A first skin check takes about half an hour and is covered by most insurance plans: your history, a full-body exam, a closer look at anything unusual and, if needed, a biopsy the same day.

Check-in
Forms arrive by text before your visit, so check-in takes two minutes. Bring your insurance card and a photo ID.
0:05
Your history
Sunburns, tanning, family history and any spot you’ve noticed. Point it out; you know your skin better than anyone.

A closer look at a changed mole, twelve minutes in
0:10
Head-to-toe exam
Scalp, face, nails, between the toes and the places the sun never reaches, in good light. A chaperone is yours on request.
0:20
Dermoscopy
Anything unusual goes under a dermatoscope, a lit magnifier that shows the pattern below the surface, and is photographed for your chart.

Same-day biopsy, twenty-five minutes in

Plan in plain words
What’s harmless, what to watch and what we’d test. Prescriptions go straight to your pharmacy before you leave.
0:30
Same-day biopsy
If a spot needs testing, it takes a few minutes with numbing. Results come back in 7 to 10 days and we call you either way.
Median wait for a new patient, 2025
9
days,
not nine weeks.

That’s how long a new patient waits for a first visit here. We hold same-week slots for changing moles and keep a cancellation list that actually calls you back.

“Dr. Ruark found a spot on my shoulder I had never seen. Biopsy that afternoon, Mohs two weeks later, and a scar my husband can’t find.”

Before you book.
Anything else, ask Marisa at the front desk. She checks your coverage, sorts out referrals and books your visit.
Do I need a referral?
Most PPO plans don’t require one. HMO plans and some Medicare Advantage plans do; Marisa checks yours before your visit and requests it if needed.
