Humanizing Telehealth Sleep Care

Meet our team of board-certified clinicians grounded in Frederick, Maryland, bringing academic rigor to your home.

Our Four Core Care Principles

1. Patient-Centered Care

We treat the individual, not just the diagnosis. We take the time to understand your lifestyle and sleep goals to craft a plan that fits you.

2. Academic Rigor

Our clinicians hold board certifications in Sleep Medicine and Internal Medicine, ensuring evidence-based clinical practices and advanced diagnostic methods.

3. Telehealth Convenience

Quality healthcare should be accessible. By eliminating commutes and waiting rooms, we fit specialist care into your busy schedule.

4. Local Maryland Roots

Even though we are virtual, we are locally based in Frederick, Maryland. We coordinate directly with your local PCPs and pharmacies.

Rooted in Frederick. Practicing Statewide.
