Dr. Campbell is a native Chicagoan with a BS and MS from the University of Illinois, a DO degree from the Kirksville College of Osteopathic Medicine, and a Family Medicine residency from the Medical College of Georgia.  Board certified in Family Medicine for over 25 years, she also holds certification from the American Board of Integrative Medicine.

For thirteen years, Dr. Campbell practiced indigent healthcare in a Community Health Center, but since 2005 has championed a solo, concierge-style integrative, holistic, functional medicine-based family practice.

Dr. Campbell has specialty interests– and lectures internationally on– innovative medical practice design and management, community partnerships, Functional Medicine, Bio-Identical Hormone Replacement Therapy, cardiovascular disease prevention, the oral-systemic connection, solutions to physician burnout and Vitamin D.

She began hosting interdisciplinary meet-up groups in 2010 via her “Consortium of Integrative Care Practitioners of Atlanta”. In 2017, she launched “Revolution Practice,” a concierge medicine teaching platform whereby practitioners are taught the business of how to run a successful membership-style functional medicine practice like hers.

In her spare time, Dr. Campbell enjoys live theater, gardening, healthy cooking, hiking, travel, and playtime with her husband and three college age daughters. Learn more about her and her practice at 

Dr. Izabella Wentz, Pharm.D., FASCP is a passionate, innovative and solution focused clinical pharmacist. She has had a passion for health care from a very early age, inspired by her mother, Dr. Marta Nowosadzka, MD.

Fascinated by science and the impact of substances on the human body, Izabella decided to pursue a degree in pharmacy with a dream of one day finding a cure for a disease.

An avid learner and goal-oriented student, she received the PharmD. Degree (Doctor of Pharmacy) from the Midwestern University Chicago College of Pharmacy at the age of 23.

After graduation, she excelled at numerous roles including working as a community pharmacist, a clinical consulting pharmacist and later a medication safety pharmacist. She is a Fellow of the American Society of Consultant Pharmacists and holds certifications in Medication Therapy Management as well as Advanced Diabetes Care.

After moving to a new city, she was given the opportunity to lead a statewide medication safety initiative, transitioning to a career in medication safety and healthcare quality improvement. There, she developed an expertise about the whole systems approach, rapid tests of small change; outcomes tracking and root cause analysis.

After two years of researching Hashimoto’s and Hypothyroidism, she decided to combine emerging knowledge with her quality improvement expertise to run rapid tests of change on herself that led her to discover the root cause of her condition. She has summarized three years of research and two years of testing in her book: Hashimoto’s Thyroiditis: Lifestyle Interventions for Finding and Treating the Root Cause.

In 2017, she published another #1 NY Times bestselling book, Hashimoto’s Protocol: A 90-Day Plan for Reversing Thyroid Symptoms and Getting Your Life Back – a more step-by-step, in-depth plan that streamlines the most effective interventions to reverse the autoimmune damage at the root of Hashimoto’s.

Her most recent publication, Hashimoto’s: Food Pharmacology: Nutrition Protocols and Healing Recipes to Take Charge of Your Thyroid Health, is a cookbook featuring 125 delicious recipes with thyroid-supporting nutrients, strategies for making dietary changes an easy part of one’s life, and protocols that can help transform the body into a safe place so that it can receive the foods needed to heal.

During her time as a consultant pharmacist, Dr. Wentz worked as part of an interdisciplinary team consulting on thousands of complicated patient cases, often caused by rare disorders. She was regarded as an expert in clinical pharmacology and would be called to investigate cause and effect by performing comprehensive medication therapy reviews to help identify and resolve adverse drug events. She quickly became well versed in finding and evaluating emerging research to help address her clients’ unique challenges. Although trained as a pharmacist, she was an ardent champion for lifestyle interventions, which often helped patients much more than any medications.
