Catherine Waller - About Page@2x

Catherine Waller MD

Medical Director

Dr. Waller received her medical degree (MD) from Wayne State University (Detroit) in 1983 and completed her Family Practice residency at St. John Hospital (Detroit) in 1986. After 20 years in practice, she grew frustrated with the ineffectiveness of the traditional healthcare system which encouraged the use of medications to mask symptoms without really resolving the underlying causes of illness or helping patients become truly healthy.

In 2003, after discovering the specialties of Anti-aging and Functional Medicine, she enrolled in a Fellowship program and by 2005 had become one of the first 20 physicians in the United States to become Board Certified in Anti-aging and Functional Medicine.

Once she began practicing Anti-aging and Functional Medicine, she was amazed at the results. For the first time, she began seeing patients achieve optimal wellness, reverse chronic health problems, regain their independence, and feel like themselves again. Witnessing these miraculous transformations on a daily basis is now the favorite part of her job.

 As the practice grew from a one room office in 2005 to the beautiful 5,500 sq. ft multi-disciplinary Waller Wellness Center that it is now, Dr. Waller's role has grown, too. To better help the thousands of new patients walking through the Waller Wellness Center doors, Dr. Waller hand-picked talented practitioners and trained them in Functional Medicine. She now has several Nurse Practitioners and Physician Assistants trained by her and she continues to be available to them for supervision and mentoring.

 In addition to overseeing the quality of care at the Waller Wellness Center as the Medical Director, Dr. Waller oversees business management, marketing, operations and program development. When she isn’t working, she enjoys building puzzles, playing board games, going to movies, collecting miniatures, and spending time on the beach at her vacation home up north.

Pamela Thomas - About Page@2x

Pamela N. Thomas PA-C

Physician Assistant

Pamela Thomas completed her master’s degree in Physician Assistant Studies at Wayne State University (Detroit) in 2009 and holds an additional master’s degree in Exercise Physiology from Northeastern University (Boston). 

In her early career, she assisted patients with chronic conditions such as cardiovascular disease and diabetes modify their lifestyles through exercise and proper nutrition. She has worked in a hospital setting and also in both Cardiology and OB/GYN private practices before coming to the Waller Wellness Center.

Pamela became a PA with hopes of using a preventative medicine approach but quickly realized that this was not possible in the current healthcare system. When she became frustrated with traditional medicine, Pamela began studying alternative medicine approaches and discovered the principles of Functional Medicine. She now has extensive training in Functional Medicine from both the Institute for Functional Medicine and Dr. Waller.

Pamela has found Functional Medicine incredibly helpful on her own health journey, and her goal is to help each patient identify and address the underlying causes that may be triggering their symptoms. She loves connecting with and empowering people to transform their health, ensuring that they can enjoy optimal health and vitality throughout all stages of life.

Sharon Meyer - About Page@2x

Sharon Meyer, RD

Registered Dietitian

Sharon has been a registered dietician since 1976 and has practiced Functional Medicine for the past 15 years. She works one-on-one with patients, helping them make the nutritional changes they need to take charge of their health. Her goal is to help you become the healthiest version of yourself with less medication.

Functional Medicine views food as medicine, and even small changes in your diet can yield dramatic improvement in symptoms. Sharon doesn’t see herself as the “food police.” She wants clients to leave her office with step-by-step practical guidance, thinking to themselves, “I can do that!”
