This artistic ability, combined with an innate desire to help others, led Dr. Schoemann to pursue a career in plastic surgery, which he felt allowed him to balance his passion for art and science. Prior to specializing in cosmetic surgery, Dr. Schoemann was a pediatric plastic surgeon. He found it incredibly rewarding to change a young child’s life and now offers the same impactful, life-changing results to adults at his private practice, Schoemann Plastic Surgery Center.

Ming Dai

L.A.C., Acupuncture

Ming Dai has successfully treated patients with acupuncture for over 30 years. Although first trained in Western medicine, as a graduate of Shank Hai Jiao Tong University, she later realized, through personal family experience, that, in many respects, Western medicine was limited to focusing on symptoms. She witnessed Traditional Chinese Medicine go further, not only reversing desperate health symptoms, but frequently rendering the patient free from the actual cause of their symptoms.

You can live pain free, without painkillers. Ming’s acupuncture technique is like magic, it gives relief from pain in just minutes. Ming is uniquely trained in this technique.
