Educator / Speaker / Writer

Dr. Blumenthal is an occupational physician, with training in pharmacology and toxicology and clinical experience in trauma.  He received his M.D. degree from the medical school in Bonn, Germany, and his M.P.H. from the joint occupational medicine program at University of Medicine and Dentistry of New Jersey and Rutgers. He is a Diplomate of the American Board of Preventive Medicine in Occupational Medicine as well as the American Board of Independent Medical Examiners.


Dr. Blumenthal enjoys teaching and speaking assignments. He holds an appointment as Clinical Assistant Professor of Medicine at the Rutgers - NJMS.  Locally, he has served as President of the Essex County Medical Society in 2003/4.  Regionally, he has chaired the Council on Communications 2003/5 and has served on the Council on Legislature and the Bioterrorism Task Force.  Presently, he serves on the Bioethics Committee and as First Vice President of the Medical Society on New Jersey.  Nationally, he has served as Speaker of the House of Delegates of the American College of Occupational and Environmental Medicine and as member of the Executive Committee of that College in 2004/5.  He is a former member of ACOEM’s Board.


Dr. Blumenthal's training and professional experience make him resourceful. After a medical residency he entered successive fellowships in clinical pharmacology and pharmacokinetics while teaching as an instructor of medicine at Tulane and SUNY at Buffalo. For seven years, he worked at Hoffmann-LaRoche's Clinical Pharmacology Unit at Newark Beth Israel Medical Center.  He was the first to measure plasma concentrations of nitroglycerin in man, and also the first to demonstrate saccharin in the cord blood of newborns. 


While working on his doctoral thesis in a biochemistry lab followed by his years as research physician, Dr. Blumenthal underwent the mandated medical screening programs. The 'repetitive exposure' to occupational medicine raised his interest in this discipline and resulted in a career change in 1984.


In the eighties, when industry favored in-house corporate health programs Dr. Blumenthal served as Medical Director of ITT's Communication Services Group and later of Cyanamid's Shulton ('Old Spice') Group. During both assignments he built comprehensive medical programs at corporate headquarters in New Jersey as well as at out of state production facilities. He conducted voluntary annual examinations and headed a full spectrum of wellness programs, including employee assistance. He took care of injured employees, assured OSHA compliance by designing special survey programs and became a member of the corporate safety team. Both assignments ended after corporate buyouts.


The nineties saw industry outsourcing its corporate health programs. Dr. Blumenthal joined a chain of clinics, which later became part of Concentra®. He started up their Elizabeth facility where he served as its first Clinic Medical Director. His clinical experience of 12,000 hours as an emergency physician came in handy.  He has worked as an independent medical consultant and has developed strong professional ties with other consulting physicians.  This helped in his role as Regional Medical Director, New Jersey of IMX Medical Management Services, Inc. from 2004 to 2019.  He continues to mentor other examiners. Since 1992, Dr. Blumenthal has conducted over 36,000 independent medical examinations. 


Dr. Blumenthal has worked with New Jersey based multinational corporations since 1977. His consulting assignments at home and abroad, have included the State of New Jersey, Glaxo, Pfizer, PSE&G, Toshiba America, Cyanamid Canada and the Virgin Island Telephone Company.  Dr. Blumenthal and his wife Marianne have raised three children in Maplewood, NJ.
