Rhéo
Functional Medicine
Rhéo is our signature functional medicine program, rooted in functional medicine and pharmacy. From the Greek rhéō, meaning “to flow,” Rhéo is inspired by the science of rheology, the study of how systems move and adapt. Health is never static; it is always in motion. Our approach focuses on restoring the body’s natural flow rather than simply managing symptoms.



Dr. Lana Saad Sherr
I’m Lana the Pharmacist, a Doctor of Pharmacy and a Functional Medicine Pharmacist dedicated to helping people identify the root causes of their health concerns and restore balance to their bodies, one system at a time.
My career began in a chronic disease management clinic and academia. I currently serve as Assistant Dean for Professional Affairs and Associate Professor of Pharmacy at the University of Maryland Eastern Shore School of Pharmacy, where I have spent more than a decade educating and mentoring future healthcare professionals. Throughout my academic career, I have remained committed to patient-centered care and advancing approaches that support long-term health and wellness.
Today, I am returning to clinical practice with renewed purpose: helping patients feel better, regain control of their health, and achieve lasting wellness through a functional medicine approach that focuses on identifying and addressing the root causes of illness.
As a mother, wife, sister, and daughter, I understand how important it is to feel your best, not only for yourself but for the people you love. That personal passion drives the care I provide. I bring the same commitment to my patients and their families, focusing particularly on women’s health, an area that does not always receive the attention it deserves, as well as functional medicine.
My clinical approach focuses on identifying the root causes of illness rather than simply managing symptoms. By addressing health system by system and using personalized nutrition, lifestyle strategies, and evidence-based medicine, I work with patients to support long-term health and vitality.
I founded Rhéo Functional Medicine with the vision of helping people restore flow in their health. The name Rhéo comes from the Greek root meaning “to flow,” reflecting my belief that when the body’s systems are supported and working together, health can move in the right direction again.
