About Thomas Mullady

With 48 years of practice under his belt, Dr. Thomas Mullady is the most senior member of the Diagnostic Center staff. The doctor is a New York State native who attended Johns Hopkins University on a full scholarship, earning both his bachelor of science and a medical degree from the school. Dr. Mullady chose to practice internal medicine because he enjoys working with patients and evaluating their problems.

Dr. Mullady has always been a Diagnostic Center physician. He joined the McGuire and Rawlings-led group upon completion of his residency in 1962 after learning about the opportunity through a listing in a medical journal. He appreciates his practice’s long-standing relationship with Parkridge, noting that it has always been a convenient resource for patients.

Dr. Mullady and his wife have five grown children, and the doctor comments that his greatest accomplishment has been successfully raising a family. In his spare time, Dr. Mullady enjoys golfing, reading and spending time with his family. He also writes, and notes that he may consider writing a book when he retires.
