About

Rep. William PetitDr. William A. Petit, Jr.  was sworn in for his first term in office as State Representative for the 22nd District on January 4, 2017 and proudly represents the 22nd General Assembly District covering the towns of Plainville and New Britain.

For the 2017 and 2018 legislative sessions, Rep. Petit will serve on the Appropriations, Public Health, and Commerce Committees.

Dr. Petit grew up helping his father work the register in the Petit General Store on Whiting Street in Plainville before graduating from Plainville High School in 1974. He then attended Dartmouth College for his undergraduate degree, and then the University of Pittsburgh School of Medicine. He followed this with a residency at the Strong Memorial Hospital at the University of Rochester’s School of Medicine and Dentistry and a Fellowship in Endocrinology and Metabolism at the Yale University School of Medicine.

Dr. Petit operated a private practice in Plainville from 1989-2007 with offices on East Street, Washington Street, and Whiting Street. In 1997 he was selected to become the Medical Director of the Joslin Diabetes Center at New Britain General Hospital (now the Central Hospital of Connecticut). Dr. Petit also served as Plainville’s Director of Public Health from 1994-2008.

After tragedy struck his family in 2007, Dr. Petit, with the help of friends and family, created the Petit Family Foundation as a 501c3 dedicated to maintaining the legacies of his wife, Jennifer Hawke-Petit, and two daughters, Hayley and Michaela Petit. The Foundation’s funds are given to foster the education of young people, especially women in the sciences; to improve the lives of those affected by chronic illnesses; and to support efforts to protect and help those affected by violence.

The first board meeting was in December 2007, and since then, Dr. Petit has volunteered for the foundation and has served as its president. In the past nine years, the Petit Family Foundation has given out over $2 million dollars in grants and sponsorships to individuals and organizations that espouse the foundation’s mission.

In addition to his work with the Petit Family Foundation, Dr. Petit serves his community in the following positions:

  • Member, Men Make a Difference, Men Against Domestic Violence Committee
  • Chairman, CT State Medical Society’s Charitable Trust
  • Member, CT Science Center’s Women in Science Steering Committee
  • Member, Health Affairs Board of Fellows for the Quinnipiac University Frank Netter School of Medicine
  • Chairman of Hayley’s Hope and Michaela’s Miracle Memorial MS Fund, which has granted over $450,000 for MS programs and scholarships in the state

Dr. Petit married his wife Christine in 2012, who is from Bristol. They are the proud parents of a very active 3-year-old, William III, who attends pre-school in Plainville.
