Dr. Neimark is a board-certified family physician, who attended the Ohio State University College of Medicine where he graduated with honors in 1981 and was elected into the scholastic medical honor society, Alpha Omega Alpha. While completing his internship, Dr. Neimark became disenchanted with traditional medicine's focus on treating the symptoms of disease, rather than dealing with the root cause. This led him to create mdPersonal Concierge Family Medicine in 2005, in order to give patients the extra time and attention needed in order to heal more fully.
Then in 2011, Dr. Neimark completed a two-year post-doctoral training program in Functional Medicine through The Academy of Functional Medicine and Genomics under the personal tutelage of Dr. Charles Gant, M.D., Ph.D. where he became certified in Functional Medicine.
In his quest to help patients heal, he became fascinated with the healing potential of stem cells, which led to his popular TEDx talk in July 2019 on "The Promise of Stem Cell Therapy." Then, in 2024, he expanded his stem cell treatments to include the work of Todd Ovokaitys, M.D. who pioneered the use of the patented SONGLaser to activate a powerful newborn caliber stem cell called the VSEL (very small embryonic like) stem cell, which can turn back the biological clock at the DNA level to improve patients' health, vitality and health span.
Dr. Neimark is in private practice in Irvine, CA, where he serves as the founder and medical director of mdPersonal Concierge Functional Medicine, successfully applying the principles of mind/body health, functional medicine, and stem cell therapies to help his patients overcome illness and work towards optimal health and greater physical and emotional well-being. He also serves on the volunteer faculty at Touro University Medical School, training third and fourth year medical students in family medicine.
