Dr. Pass completed fifteen years as a general practitioner in Nova Scotia, while an adjunct member of the Dalhousie University Faculty of Dentistry and Department of Physics. He then became Director of Oral and Maxillofacial Radiology at Dalhousie University for ten years. Following his first retirement, he served two years as a Patent Examiner in medical imaging for the U.S. Patent Office in Arlington, Virginia. He then joined the Department of Oral Diagnosis and Radiology at the Howard University School of Dentistry, in Washington, DC, and retired for the second time after 18 years. He has been Professor Emeritus for the past two years.

Dr. Pass is a recognized expert in radiation physics and has written numerous peer reviewed research articles. He also served as a Graduate Professor, Department of Physics and Astronomy, at Howard University. He continues forty years of research in radiation physics that began with pioneering collaborative work on the use of dental enamel and other calcified biological tissues for radiation accident dosimetry. Presently he is collaborating on studies in forensic archaeology.

Dr. Pass is a member of the American Board of Oral and Maxillofacial Radiology, a member of the American  Academy of Oral and Maxillofacial Radiology, an Honorary Member of the Canadian Academy of Oral and Maxillofacial Radiology, and a member of the International Association of DentoMaxillofacial Radiology.
