My old family doc was a DO, I never had a problem with her.
My grandfather, his two sisters, his mother, and her two sisters and two brothers were all Osteopathic physicians. My grandmother and another aunt attended nursing school at the same osteopathic college (Kirksville, MO, the “home” of osteopathy). My grandfather was also a surgeon.
We used a family practice group of osteopaths in Oklahoma and got excellent care, including an occasional prod of the pain in my hip by the “Old Doc.” The practice also included his sister, who did my prenatal care and deliveries, the sister’s husband, and a daughter (our GP) and son.
