North Side of the Square Insurance, Inc. (now First MainStreet Insurance DBA North Side Insurance) was established in June of 1988 by Davis County Savings Bank (now Success Bank) and Bill Van Cleave, who was the owner of two agencies previously purchased from Robert Hockersmith and Audie Redmond. In 1989, an agency owned by J. Dean Baughman was incorporated into the North Side office located at 106 East Jefferson in Bloomfield.
In 1991, North Side of the Square Insurance purchased Weber Insurance in Centerville. The original office was located at 103 East Van Buren in Centerville, then moved to the current location of 109 West Van Buren in 1994.
In 2008 the corporation name was changed from North Side of the Square Insurance to North Side Insurance.
In 2015, North Side Insurance became an affiliate of TrueNorth Companies, L.C. The corporation name changed from North Side Insurance to First MainStreet Insurance, DBA North Side Insurance. Both offices continue to be staffed by local agents who are committed to providing excellent service to their communities: Lisa Bell and Lynn Bumsted in Bloomfield, and Amy Gonnerman and Sandi Kauzlarich in Centerville. Together, the team boasts a combined experience spanning several decades in the insurance industry.
