Dr. Nathan then went on to Albert Einstein College of Medicine in New York where, following his selection as chief resident, received his certificate in Oral and Maxillofacial Surgery in 1985.

In 1985, Dr. Nathan began his private practice career in Oral and Maxillofacial surgery with Dr. Tobin Finizio, who had established the practice in 1969. Dr. Nathan immediately became involved in teaching graduate dentistry through the Prince Georges Hospital Dental residency program as well as providing hundreds of hours of Continuing Education to the dental community. He also served two terms as Chairman of the Department of Oral and Maxillofacial Surgery at Shady Grove Adventist Hospital. In 1996, Dr. Nathan was elected the President of the Southern Maryland Dental Society, Maryland’s largest American Dental Association component. He has also served as a Maryland State Dental Association delegate for over twenty years. In 1998, the prestigious American College of Dentists bestowed an additional degree upon Dr. Nathan (Fellow of the American College of Dentists) for his combined contributions to Oral Surgery, the dental professional community, and to oral surgery/dental publications.

Dr. Nathan is an active member in numerous other professional societies including; The American College of Oral and Maxillofacial Surgeons, The International, American and Maryland Association of Oral and Maxillofacial Surgery Societies, the American Anesthesia Society, Alpha Omega Dental Fraternity, the American Academy of Osseointegration and the American and National Dental Associations. Additionally, he is a member of multiple continuing education study clubs, earning 50-100 CE hours each year. In 2014, Dr. Nathan served as the Chairman of the Mid Maryland Mission of Mercy which provided dental/surgical procedures to well over 1,200 needy patients. This resulted in excess of $1,200,000 of free dental care. For that effort, Dr. Nathan received a Certificate of Appreciation from the Maryland State Dental Association’s House of Delegates.

Dr. Nathan has been selected, a Washingtonian Magazine “Best Dentist” four times, along with a selection to America’s Top Dentist. He also served as the University of Maryland Athletic Teams’ Oral Surgeon for fifteen years.

Dr. Nathan is one of the original participants of The Maryland Foundation of Dentistry for the Handicapped/ DDS Program, which was formed in 1989 by caring dentists who were willing to help underserved Marylanders access dental care. The Donated Dental Services program provides life-changing dental care at no cost to low-income adults, disabled by chronic health conditions. Moreover, Dr. Nathan is an original provider for The Holocaust Survivors Program, which launched in 2011 in the Washington, D.C. area. This group, through the Jewish Social Service Agency (JSSA), provides pro bono dental treatment for low-income survivors of the Holocaust.

When Dr. Nathan first began in 1985, there was one full-time office and two fledgling satellite offices that had a combined total of 3,000 feet of space and just two full-time surgeons. Currently, through his efforts of organic growth of the 3 existing locations, acquisition of other practices, the opening of new “start-up” offices and additional surgeons, the organization has grown to eight locations. These offices span over seventy miles, from Frederick to Annapolis Maryland encompassing Anne Arundel, Carroll, Frederick, Howard, Montgomery, and Prince Georges counties along with D.C. and Northern Virginia. MOSA has grown to occupy approximately 30,000 square feet, with thirteen surgeons and one hundred staff members. In 1995, Dr. Nathan renamed the practice MARYLAND ORAL SURGERY ASSOCIATES. He also established a separate management company, MOSA Management LLC (MOSA-M), which provides comprehensive administrative responsibilities for all eight locations, and he serves as its President and CEO.

MOSA Management services include Accounting, with an in-house CPA and Staff Accountants, Accounts Payable, and Marketing and Continued Education for the dental community as well as the MOSA surgeons. Our Human Relations Department’s responsibilities include recruiting, vetting and hiring of all staff together with administrating benefits, monitoring OSHA, Infection Control, HIPAA compliance, and assuring employee rights and responsibilities.  MOSA-M has several Senior level Insurance Administrators and Trainers, each with over 20 years of experience, who review all claims and patient refunds, in addition to providing in-house individual office staff-member training on the latest insurance coding and insurance requirements.  Furthermore, the management team acquires the surgeons’ hospital and insurance credentials and negotiates for the highest possible fee reimbursements from the 100+ participating insurance companies. MOSA-M has negotiated Hospital-level discounted pricing for dental implants, medical supplies, and surgical/ dental equipment. The management company also acquires and negotiates staff health, dental, and disability insurance, as well as monitors a Pension and Profit-sharing plan along with a matching 401K plan.

In 2016, after thirty-one years as a practicing surgeon, Dr. Nathan transitioned to committing his full-time efforts to the administration of the MOSA Management. Maryland Oral Surgery Associates is now one of the largest privately-owned Oral/ Maxillofacial Surgery practices in the United States. Along with a large and highly experienced team, he helps to keep the operations in the eight Maryland locations running smoothly. These efforts allow the MOSA Surgeons and Staff to concentrate their full attention to top quality, “state of the art” surgical and patient care that MOSA has been known for since its inception fifty years ago. MOSA doctors have been honored to care for nearly 400,000 patients since its inception in 1969. We are proudly celebrating our Golden 50TH anniversary in 2019!

MOSA Management’s future plan is to continue to widen its base of the organization by further expanding existing offices, opening new offices, along with acquiring existing practices in the Maryland, D.C., and Virginia areas.  It is also increasing its management/consulting services to many members within the dental and medical community- locally and across the country. MOSA Management’s most important goals are to keep Maryland Oral Surgery Associates at its peak position within the Dental and Medical community by providing the highest level of state of -the art patient care and concern.

Dr. Nathan loves spending his free time with his wife (and MOSA consultant) Danielle, three wonderful children, their spouses, extended family, and his many special friends. His hobbies include skiing, exercising, traveling, fishing, kayaking, reading and community activities.
