Say hello to the team.

Grant Cox, MD

Grant Cox is excited to be a part creating OB/GYN Specialists of Tulsa. He brings to the practice considerable knowledge and skill in all aspects of OB/GYN, especially infertility and gynecologic surgery. He finds it most rewarding when he can help an infertile couple or a patient with recurrent miscarriages conceive and carry a baby to birth. He feels that all deliveries are special, but those couples that have been through challenges create a moment of absolute awe when they hold their baby for the first time.

Paul Gehring, MD

Dr. Paul Gehring moved to Tulsa in 1994 with his wife, Dr. Gena Gray. He originally practiced at an infertility clinic to pursue his interest in reproductive surgery. After three years, he missed doing all aspects of OB/GYN and joined a full-time OB/GYN practice where he held many administrative positions. He is beyond excited about starting OB/GYN Specialists of Tulsa, where he can utilize his practical knowledge to create the best possible patient experience.
