Jon Sidoti, CPA

After graduating from Northeastern University and obtaining his CPA license, Jon Sidoti joined the international accounting firm that now bears the name KPMG.   Working with both large and small companies, Mr. Sidoti enjoyed a wide range of accounting, tax and business auditing experiences but found he preferred working with smaller companies.  “I clearly enjoyed working with closely-held business and their owners” says Sidoti. 

After KPMG, Sidoti joined a Plymouth, MA consulting firm, where he became a partner in charge of tax planning.  In October 1988, Sidoti founded the firm which has evolved into Jon C. Sidoti, PC.

Jon lives in Plymouth with his wife Jean and has 3 grown children.  He is an avid cyclist and enjoys skiing.
