Neil F. Neimark, M.D.
Founder and Director mdPersonal Concierge Medicine


Dr. Neimark is a board certified family physician, 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 searching for the underlying causes, lifestyle habits and emotional states of mind that lead to true health and healing.

He realized that even with the best of medical care and technology, patients were unable to break out of the cycle of recurring illness. Frustrated with his inability to help patients stay healthy, he began searching out the scientific basis for achieving optimal health, finding the root causes of disease and searching out means for truly preventing disease, rather than just relying on early detection of disease.

In 1984, he attended courses at the Mind/Body Clinic of New England Deaconess Hospital, Harvard Medical School, where he met Herbert Benson, M.D. and Joan Borysenko, Ph.D., pioneers in the field of mind/body health and psychoneuroimmunology. This event redirected his life. With this newfound focus, he finished his residency and went on to complete a fellowship in academic medicine, focusing on the mind/body connection.

Dr. Neimark now serves as an assistant clinical professor in the Department of Family Practice, University of California, Irvine. He is in private practice in Irvine, where he successfully applies the principles of mind/body medicine to help his patients overcome illness and work towards optimal health and greater physical and emotional well-being.

Dr. Neimark is happily married and lives with his wife, Marta and their three children, Chris, Jenny and Arianna and their two dogs Gizmo and Frankie. He loves spending time with his family just laughing and "hanging out." He is a songwriter, guitarist and loves writing his own original love songs in the "pop/rock/ballad" style. He dreams of one day playing lead guitar like Carlos Santana, writing lyrics like Sting, melody lines like Billy Joel and having Bette Middler sing one of his ballads on the radio!

Stacy Vencill
Physician Assistant and Expert Botox/Filler Injector


Stacy Vencill is a graduate from the George Washington University Physician Assistant Program, in Washington DC. At GWU, she completed a Masters of Science and a Masters of Public Health, specializing in Maternal and Child Health.

After graduation from PA school, Stacy realized that she could not pick just one specialty in medicine. And now, with experience in both Family Medicine and Aesthetics/Anti-Aging, she feels fortunate to have the opportunity to work in such diverse areas of medicine. “As practitioners, we have an obligation to be knowledgeable about the advances in medical technology of all specialties,” according to Stacy. Stacy enjoys helping clients look as good as they feel and therefore finds the field of Aesthetics/Anti-Aging very rewarding as well.

She feels privileged to get to know her patients personally and care for them as she would a family member. Her partnership with Dr. Neimark further compliments these priorities by offering every comprehensive care to every patient and ensuring every patient is completely satisfied with any procedure.

Although Stacy has experience with a vast number of laser procedures, she has developed a passion for injectables over the last few years which have driven her to complete advanced training Botox and dermal fillers (such as Restylane, Juvederm, Radiesse and Artefill). She particularly enjoys doing Botox and fillers because of the “artistic ability that is required to augment the face with natural and subtle accents.” In addition, she is a national trainer for Allergan and assists other practitioners in the administration of Botox and multiple dermal fillers.

Stacy lives with her husband, her son Luke, daughter Emma and her two dogs, Ripley and Sawyer, in Tustin Ranch. She enjoys Pilates, interior design projects, traveling, participating in medical missions and spending time with her family.

Cathy Mullally has been Dr. Neimark's nurse, assistant and friend for over twenty-one years now. For everyone who knows her, she is the one who greets you with a warm, inviting smile and knows all about your family, your kids and your relatives - the good and the bad.

She is always there with a smile to do all the hard work it takes to make a practice run efficiently: from calling in prescriptions, to getting Dr. Neimark to answer your questions, to making sure the specialists get all the records and labs they need prior to your visit, to fighting with the labs to make sure you get the proper reimbursement.
