A husband-and-wife team, four decades at Mayo Clinic
Skilled, caring physicians with an extraordinary breadth of training in both conventional and integrative medicine — now devoted entirely to you.
Dr. Angela O’Neil, MD
Born and raised in Minnesota, Dr. O’Neil attended the University of Minnesota Medical School and practiced at Mayo Clinic for 20 years — serving as Assistant Professor and Assistant Dean at Mayo Medical School, and earning numerous teaching and service awards.
For much of her career she practiced obstetrics and holds a deep, lifelong interest in women’s health. She trained under Dr. Andrew Weil, completing his fellowship at the University of Arizona Center for Integrative Medicine. Her philosophy: every person has an innate ability to heal — mind, body and spirit.
Dr. Robert Sheeler, MD
Originally from Washington, D.C., Dr. Sheeler trained at UC San Diego and spent over 20 years at Mayo Clinic in prestigious leadership roles — Medical Editor of the Mayo Clinic Health Letter, Clinical Practice Chair of Family Medicine, and Family Medicine Clerkship Director for a decade.
He chaired the Neuro-Psychiatric Medicine Task Force, overseeing more than $1 billion in specialty-medication purchasing. A UCNS-certified headache subspecialist, Reiki Master and certified Taiji-Qigong teacher, he blends rigorous science with deeper layers of healing — and a passion for understanding what gives each patient meaning and vitality.
