Summary

Dr. Lem is a Board Certified Oral and Maxillofacial Surgeon. He is one of the very few oral surgeons who have dual degrees (M.D. & D.D.S.). Dr. Lem has a California general anesthesia license which allows him to administer I.V. sedation in our office for the comfort of our patients. This means he is exceptionally well trained and adept in office-based as well as hospital-based oral surgery.
He has been rigorously trained in both medicine and dentistry for nine years in Los Angeles and the East Coast. Dr. Lem is a graduate of the UCLA School of Dentistry and the University of Connecticut Medical School. He completed his oral and maxillofacial surgery residency at the University of Connecticut, which included 6 months as an anesthesiologist and critical care physician. He has 20+ years of dental implant experience.
Why Oral Surgeons are unique in the dental profession
They are the surgical specialists of the dental profession. Their experience in general surgery, medicine, anesthesia and dentistry uniquely qualify them to diagnose, treat and manage conditions, injuries, and aesthetics aspects of the mouth, teeth, jaws and face. Maxillofacial surgeons are initially qualified in dentistry and have undergone further medical training.
