If you have Medicaid, Sianna Bates CRNP at Warren Clinic, Broken Arrow saved my son's life after we found her. He'd given up on and by the medical system prior to seeing her. And after being a nurse for 50 years, I've been appalled at what lack of concern, professionalism, and follow-up he'd been subjected to for years prior to finding her. I would not hesitate to recommend her for her care, compassion and diagnostic abilities.
