Breathing and sleep are connected.
Your care should be too.

Where Pulmonary Science Meets Sleep Medicine.

Established to bring the depth and rigor of academic medicine to Frisco's first independent pulmonary and sleep care.

Clinical Care

Five pathways.
One system of care.

Three disciplines.
One evaluation.

Coordinated within a single clinical evaluation.

You deserve to know why.

Why you feel the way you do. Why a test is worth doing. Why a treatment is right for you. And what comes next. We will listen, explain our thinking, and be honest when the answer isn't simple.

Your care should make sense to you, not just to us.

Physician-led care.

a better question.
