I used precheck before my appointment so when I arrived I only waited a few minutes to see the doctor. She was very prompt, answered all my questions, explained my choices for treatment and followed up promptly with ordering my new meds.

The office was inviting and the wait time was very short. I was treated with respect the entire time and never left waiting in the exam room for long periods not knowing when I’d be seen.

I consistently receive thoughtful, patient-centered care from her, and I always leave feeling confident about my health plan.
