Over A Century Of Serving Southeastern Wisconsin
Our History
Rooted in Community.
Built for What's Next.
Since 1918, Ixonia Bank has grown alongside the people, businesses and communities we serve. Through generations of change, opportunity and challenge, we’ve remained grounded in the relationships and local roots that shaped us from the beginning.
Today, with more than $1 billion in assets, we carry that legacy forward with the same commitment to local decision-making, personal service and helping our clients and communities thrive.
In April 2017, a group of businessmen in the Ixonia area began conversations to organize a new bank. They raised $10,000 in capital, named the bank Ixonia State Bank, and opened for operations in 1918.
The bank bought land in 1954, and began constructing its new building in 1955. January 1, 1956, the new building opened, with eight employees and featured Jefferson County’s first drive-up window.
In 1976, the Bank remodeled and expanded its Ixonia office to accommodate its employee growth. Improvements included air conditioning and an additional 4,000 square feet.
In the 1990s, Ixonia State Bank added three branches: Watertown-Oakridge Court in 1990, Oconomowoc-Summit Avenue in 1994, and Watertown-Church Street in 1997.
In the 2000s, the Bank added the Dousman-Main Street branch in 2001. In 2003, the bank changed its name to ISB Community Bank.
In 2012, Sheldon B. Lubar and his family acquired majority stake in Ixonia Bancshares—then with assets around $270 million—seeing an opportunity in small- to mid-size community banking. As Chairman of the Board, Sheldon’s Vision Statement to shareholders and employees was: Soundness, Profitability, and Growth in that order. This remains a pillar of we operate at the Bank.
Harkening back to its roots, ISB Community Bank changed its name to Ixonia Bank in May 2013.
In order to better serve a growing, vibrant Oconomowoc community, Ixonia Bank opened its Lakes Plaza office in January 2018.
2020 marked a transformative time in Ixonia Bank history. Our Milwaukee Office opened January 2020, and not long after, the COVID-19 Pandemic arrived. This shifted how we did banking, but our team was able to still assist customers and businesses navigate uncertain times, including distributing over $71 million in Payment Protection Program (PPP) loans.
Continuing an extraordinary 2020, in April 2020, Ixonia Bank acquired a growing nationwide lender – Novus Home Mortgage – led by Eric Egenhoefer. Headquartered in Waukesha, Wisconsin, Novus focuses on a streamlined borrower experience through innovative technology and common-sense approach to lending.
In 2026, Ixonia Bank has surpassed $1 billion in total assets, an important milestone that reflects more than a century of relationship-driven banking and a growing demand for customized financial solutions.
What Hasn't Changed
More than a century after our story began, Ixonia Bank continues to grow, evolve and invest in the people and communities we serve.
Surpassing $1 billion in assets represents an important chapter in our history, but our focus remains on what comes next: building trusted relationships, creating opportunities and remaining a strong, independent banking partner for generations to come.
