Wauwatosa Savings Bank has officially changed its name to WaterStone Bank SSB this week. The bank has experienced significant growth in recent years, both in new branch offices and in additional product lines, according to Doug Gordon, president and chief executive officer. The bank has offices in Wauwatosa, Franklin/Hales Corners, Germantown/Menomonee Falls, Oak Creek, Oconomowoc, Pewaukee, Waukesha and West Allis. "A name change is necessary to better reflect what we are now, and what we plan to be in the future," Gordon said. "As we continue to expand geographically to other communities, ‘Wauwatosa’ does not clearly define our intentions to be the premier community bank in all the communities we serve." In February, Wauwatosa Savings invited its customers and communities to help choose the bank’s new name by completing an opinion ballot.
