John Thomas McGwire

Beloved great-grandfather, dentist, sports enthusiast

John Thomas McGwire died December 29, 2020 at the age of 83 at Mission Hospital in Mission Viejo of pneumonia caused by leukemia.

He is survived by his loving wife of 60 years, Virginia (Ginger); sons Michael, Mark, Robert, Daniel and Jay; eighteen grandchildren; and one great-granddaughter.

John McGwire was born on September 7, 1937 in Bronxville, New York. He was a man of faith who believed in service to others. He graduated from the University of Washington Dental School in 1962 and had practiced dentistry for 38 years in Pomona. He continued to work after he retired from his dental practice to ensure proper dental care for the less fortunate.

He served as president of the Pomona Chamber of Commerce and the Pomona Rotary Club, and on the board of Western University of Health Sciences in Pomona for many years.

He cherished his time with his children and shared his love of sports with them. He coached them in Little League and AYSO for 10 years. He also enjoyed cycling and playing golf.

A celebration of life is postponed due to COVID-19.
