Agency History
Colonial Insurance Services, Inc. was founded by A.B. Day in 1882.  He was the first banker in Mansfield and established the First National Bank of Mansfield.  Day served in many capacities including Selectman.  His successor was his son-in-law, Herbert E. King.  King changed the named of the insurance agency to his own.  In addition to running this insurance agency, he was treasurer of the Mansfield Cooperative Bank and Mansfield Fire Chief until his death in 1932.

His son-in-law, Charles A. Wheeler, then took over the business and ran it under the Herbert E. King agency name.  Wheeler was also active on three bank boards.  An avid scouter, he was the recipient of many awards.  His local involvement included several town building committees and the Industrial and Development Commission.  He also was a past President of Mansfield Rotary.

Ralph H. Seifert joined Wheeler in 1957, bringing an insurance background beginning in 1950.  Seifert’s involvement in the community includes founding Citizens Scholarship Foundation of Mansfield in 1961 and co-founding the Tri-Town Chamber of Commerce in 1987.  An active member of the Mansfield Industrial and Development Commission, he also served as Town Moderator, Chairman of the Downtown Advisory Committee and member of the Master Plan Commission.  He was also a past President of Rotary.

The Herbert E. King Agency and Fred E. Wills Agency merged in 1970.  The merged agencies took a new name in 1970 – New England Security Insurance Agency.  Long in title, it represented the ever expanding scope of operation and the “Seal of Security”, offering to each client an honest product at a competitive price, backed by a personal commitment from each member of the agency.  The agency sells all types of insurance available to the general public and business.  As a result of the merger, Fred Wills joined the agency with a record of community involvement that includes a past Presidency of Rotary, Industrial and Development Commission, and School Committee.

Mitchel G. Seifert joined the agency in 1978, after five years with Aetna Life and Casualty.  He became President in October of 1986.  His community involvement includes Planning Board, past President of Rotary, co-founder and first President of the Tri-Town Chamber of Commerce, and most recently Director, Chairman Finance Committee, and Chairman Planning Committee of Greater Attleboro-Taunton United Way.

1n 1994, Mitchel Seifert founded The Nurses Insurance Agency, Inc., an agency whose main focus was offering Personal Lines automobile and homeowners discount programs. 

In 1999, The Nurses Insurance Agency, Inc. purchased New England Security Insurance Agency and continued to offer automobile and homeowners discount programs in addition to all other types of insurance. 

2002 marks our 120^th year in business!  This is no small feat and something we are very proud of.  To celebrate our history, a new agency name was selected: Colonial Insurance Services, Inc.  The new name honors the ideals of our founders and represents our long-standing commitment to the local communities, and our dedication to preserving old-fashioned service while moving forward with the times.  We look forward to serving our customers for centuries to come!
