Restoring health at the root — with science, faith, and compassion.

Committed to You

You’re more than a diagnosis. Your care should be too.

At CrossBrook Medical, we believe healing begins by understanding the whole story—not just managing symptoms. Founded by Dr. Sheila Stanek, D.O., CrossBrook combines the best of traditional family medicine with a functional medicine approach that uncovers the root causes of illness.

Whether you're dealing with chronic fatigue, gut issues, long-term stress, or mystery symptoms, our telehealth care is designed to give you answers and walk with you toward lasting wellness—through science, compassion, and grace.
