About the practice
Dr. Walker is one of fourteen clinicians at Omega Ob-Gyn Associates, a women's health group that has served Arlington, Grand Prairie and Mansfield for more than forty years, and sees patients at its Grand Prairie and Arlington offices. Walker is the only clinician in the group whose biography names hormone care, and became a Menopause Society Certified Practitioner in 2025 after watching a spouse go through a hard perimenopause following a hysterectomy at 31. A nurse practitioner and two medical assistants make up a small team inside the larger group, and the site says a patient gets the same care from either clinician. Routine and high risk obstetrics and minimally invasive gynecologic surgery are part of the same job, so hormone care is one piece of a general practice rather than the whole of it. Texas patients can sometimes be seen by video when the schedule allows.
