Oral Surgery Group, INC. is the oldest practice of its kind in the State of Indiana.  Since 1930, it has been dedicated to providing the highest standards of oral surgical care to the people of Northwest Indiana.  The practice was originally located at the Gary National Bank Building in Gary, Indiana.  In 1957, the office was moved to 3195 Broadway in Glen Park in order to centralize its position in Lake and Porter Counties.  Many patients were traveling too far and the doctors needed more space to accommodate the group practice concept of health delivery.  Again, in 1978 the main office was moved to its present location in Merrillville.  We now operate an additional office in Chesterton, Indiana.  This location helps to serve Valparaiso, Michigan City, South Bend, and LaPorte.

Dr. Robert McMahon has been with Oral Surgery Group since 1978 and is a fully trained and Board certified oral and maxillofacial surgeon. He is the author of numerous scientific papers and maintains hospital affiliations with Methodist Hospitals – Northlake and Southlake campuses. He attends continuing education courses each year to provide you with the latest skills in outpatient surgery, pain management, and anesthesia. 

Recently, Oral Surgery Group, Inc. has broadened its surgical services with the addition of Doctor Basel Hajjar, a fully trained periodontal surgeon with special interests in the placements of dental implants and the diagnosis and management of diseases of the teeth, gingivae and oral mucosa.
