He grew up in Mansfield, CT and attended E.O. Smith High School.  Jack earned his Bachelor of Arts Degree from Gannon College in 1970 and graduated with his Juris Doctor Degree from the Marshall-Wythe School of Law at the College of William and Mary in 1973.  He married the love of his life Louise Marie Durr of Chesterfield Township, NJ and moved to Willimantic, CT following his graduation.  He was admitted to the Connecticut Bar in 1974, the United States Court of Appeals for the Second Circuit in 1975, and the U.S. District Court for the District of Connecticut in 1976.  He was a founding member of the firm that is known today as Guarnaccia, Connors, Kalom & Zorn, LLC and focused his practice on elder law, commercial and residential real estate, estates and probate, and estate planning.

Jack was a member of the Connecticut and Windham County Bar Associations, and the National Academy of Elder Law Attorneys.  He is a past president of the Windham County Bar Association from 2010-2012.  He was a former member of the Connecticut Bar Examining Committee.  From 1997-2008, Jack was a member of the Board of Directors of the Connecticut Attorneys Title Insurance Company (CATIC), and served on the Board of the CATIC Foundation, Inc.
