Functional medicine is team-based medicine. Meet the team behind your care.

A physician, a nurse, and the coaches and coordinators who make sure nothing falls through the cracks between visits. Every one of them talks to each other, so you never start over.

Your Care Team

Everyone on your care team talks to each other. That's not a courtesy, it's the model.

Your nutrition plan, your lifestyle prescriptions, and your health goals all point in the same direction, because the people building them communicate.

Casie Wallis, MSN, APRN, FNP-C Functional Medicine Provider

Casie is a family nurse practitioner with a background that spans more than one way of looking at the body. She first earned a Doctor of Chiropractic degree from Cleveland University in Kansas City, which shaped how she thinks about the connection between physical and mental health. She then earned her BSN from the University of Saint Mary and her MSN as a Family Nurse Practitioner from Graceland University, completing 600+ clinical hours in family medicine.

Before becoming a nurse practitioner, she spent five years as a registered nurse in women's health, postpartum care, home health across rural and underserved communities, memory care, and psychiatric nursing. That range makes her comfortable with complex cases where physical and emotional health overlap. She brings a preventive, whole-person approach to every plan she builds with you, alongside Dr. Dockery and the rest of the team.

Before joining Vitality, she spent 10 years as an orthopedic and medical-surgical nurse and charge nurse at St. Francis Hospital in Colorado Springs, where she earned her Orthopaedic Nurse Certification and received the DAISY Award for compassionate patient care. She also taught elementary school for 11 years, and that teacher's instinct shows up in every visit: she explains your labs and your plan in plain language so you leave knowing exactly what's next. Her clinical interests include gut health, hormone balance, lifestyle and nutrition, and musculoskeletal pain.

Tanveer is the first person patients see when they walk in and the last they talk to before leaving. She handles check-in and check-out, payments, and keeps the supplement and supply inventory stocked. She also manages the patient portal message queue, routing questions to the right provider, nurse, or front desk, and handles outside imaging, labs, and specialist referral paperwork to make sure it goes out correctly the first time.
