For over 130 years, Nowlan Law has stood as a pillar of legal expertise and community commitment in Janesville and the greater Rock County area. Located at 100 South Main Street, Nowlan Law's Janesville office serves as the firm's flagship location, offering a comprehensive range of legal services to include corporate law, real estate law, civil litigation, contract law, business dispute law, probate law, and more throughout southern Wisconsin.
A Rich Historical Foundation
The origins of Nowlan Law trace back to 1857 when John Winans, a 26-year-old attorney from New Jersey, established his law practice in Janesville. Winans' dedication to public service led him to roles as Janesville's mayor, a member of the Wisconsin Assembly, and a U.S. Congressman. In 1877, he partnered with Ogden Fethers, a former English literature professor, and in 1883, they welcomed Malcolm Jeffris, a young Rock County native, into the firm. These foundational figures set the precedent for a firm deeply intertwined with the growth and development of the Janesville community.
Throughout its history, Nowlan Law has played a significant role in shaping the economic landscape of the region. The firm was instrumental in the formation of key industrial entities such as the Samson Tractor Company, which later became part of the General Motors Assembly Division, and the Parker Pen Company.
