Those close, individualized connections at J. Flowers—where there is a collaborative emphasis on addressing complex health issues—align perfectly with his own philosophy of patient-centered care.

Throughout his nursing career, David has been dedicated to addressing substance abuse and addiction as well as providing healthcare for aging adults. During his work in correctional facilities, he developed a deep appreciation for inmates struggling with mental health and addiction issues.

Practicing medicine for more than 25 years as a board-certified obstetrician-gynecologist, Dr. Karmel founded her private practice, Karmel Women’s Care, in 1995 in Houston.

Nicknamed “the global gynecologist” (a reference to treating the whole person, not just the symptoms), Dr. Karmel incorporates physical, emotional, and spiritual aspects of patients in her treatment and diagnosis.

A graduate of Duke University with a degree in comparative literature, she received her medical degree from Chicago Medical School. She completed her residency in obstetrics and gynecology at Baylor College of Medicine.

Before medical school, she volunteered at a medical clinic in India, and during medical school, she gained experience in both inner-city medicine and private-sector medicine. These experiences left her with a deep understanding of the needs of the human condition.

Currently, she serves as a gynecological consultant for the Triangle Area Network Clinics, providing healthcare to the underserved in Beaumont and Orange, Texas. In her private practice, Dr. Karmel treats women from adolescence through menopause and post-menopause.

Outside of work, she enjoys spending time with family and friends, cooking, discovering new restaurants, listening to music, and taking violin lessons.
