Pickett Headshot

Shawn Pickett is the Radiation Safety Support Services Practice Director for LANDAUER Medical Physics. After practicing as a Nuclear Medicine Technologist in Texas, Shawn moved to Florida to take on a role as Supervisor of Nuclear Medicine for a large healthcare system. In that position, he identified that one of the best motivating factors to reduce radiation exposure through the healthcare system was an engaged workforce with a supportive management structure. Shawn was promoted from Supervisor to Radiation Safety Officer to Manager of Non-Invasive Cardiology, then to the Corporate Radiation and Laser Safety Officer. Now Shawn is working with LANDAUER to develop a team of Radiation Safety Officers to support clients in the medical use of radiation nationwide. Shawn has been the named RSO on over 10 medical use licenses in multiple states and he has advised hundreds of clients across the country on the safe use of radiation. Shawn has been recognized as a Subject Matter Expert in Radiation Safety for the Nuclear Medicine Technologist Certification Board and is a Certified Nuclear Medicine Technologist, Computed Tomography Technologist and Medical Laser Safety Officer. Shawn holds a Bachelor’s Degree in Radiologic Science from Midwestern State University and a Master’s Degree in Business Administration from Webster University.


Joseph Greco, MS, CHP, CLSO
Joe Greco has 30 years diversified experience working with sources of ionizing and non-ionizing radiation and management of their safe use in medical, manufacturing, R&D, and fusion reactor environments. After receiving his degree in Biology, he began his professional career as a Nuclear Medicine Technologist. He then attended graduate school and received his Master’s degree in Radiological Hygiene. He spent 5 years as an operational health physicist at Princeton Plasma Physics Lab research reactor in New Jersey. He then joined Eastman Kodak in Rochester and served as their Radiation and Laser Safety Officer for 14 years. Joe joined Upstate Medical Physics, a LANDAUER Medical Physics partner, in 2006. His specialties include nuclear medicine and PET support (assessments, acceptance testing), shielding design and calculations for various imaging modalities, radiation safety training, dosimetry, licensing and regulatory support, health physics, and laser and non-ionizing radiation safety.


James O’Brien, Jr., MMsc, DABR
