Dr. Okoro received a bachelor’s in biology from Metropolitan State University, became a licensed practical nurse and then a registered nurse, and worked as an RN before attending Ross University School of Medicine. She completed her clinical rotations in the United States and a three-year internal medicine residency at St. John’s Hospital in Detroit, Michigan. She is board-certified by the American Board of Internal Medicine (Texas medical license, 2015), the American Board of Obesity Medicine, and the American Board of Lifestyle Medicine. After practicing at Texas Health Presbyterian in Dallas and Texas Health Presbyterian Hospital in Allen, she opened her own practice.

She leads our intensive cardiac rehab, traditional cardiac rehab, and pulmonary rehab programs, where care is always physician-supervised. With deep roots in Allen, she enjoys spending time with her husband, Tochi, and their two sons, Caleb and Joshua, and serves patients from Frisco, McKinney, Plano, Dallas, and surrounding areas.

She went on to earn her master’s in nursing from the University of Texas at Arlington and became a certified nurse practitioner before transitioning to a primary care role in Dallas. Kimber is driven to uncover the root causes of disease and stop it in its tracks, and she is also passionate about aesthetics and preventative skincare. Outside of work, she is a devoted wife and mother to two energetic toddlers, Milo and Luca, and enjoys traveling with her family, reading, and Peloton workouts. Based at our Allen facility, she supports patients in our traditional and virtual cardiac rehab programs and serves patients from Frisco, McKinney, Plano, Dallas, and surrounding areas.

She earned her master’s degree in nutrition from Texas Woman’s University and completed her clinical training at Children’s Health Plano and Baylor Scott & White Health, and is credentialed through the Academy of Nutrition and Dietetics. At RescueMD, Ayesha leads the nutrition curriculum and live cooking demonstrations in our intensive cardiac rehab program, specializes in nutrition therapy for diabetes and hypertension, and supports patients with gastrointestinal disorders — helping them understand the gut-heart connection and build realistic, long-term strategies for better health. Outside of work, she enjoys volunteering and spending time with her family.

Blending science-based training with compassionate care, Alex focuses on a healthy mindset, goal setting, and long-term lifestyle strategies that help patients not only recover through cardiac rehabilitation but thrive well beyond it. Outside of work, she enjoys spending time with friends and family, traveling, and coaching club volleyball, and — with a background in pastry arts — creating culinary treats and exploring new coffee spots.

At Rehab by RescueMD, Alex designs and supervises exercise programs across our intensive, traditional, and PAD care, and leads our personal training. Learn about the role of an exercise physiologist in cardiac rehab.

Outside of my professional life, I enjoy running, staying active, and traveling to experience new places and cultures. I believe in maintaining a healthy, balanced lifestyle and bringing dedication, compassion, and a positive mindset to everything I do.
