Héctor Colón

President and CEO

Héctor Colón is the President and CEO of Lutheran Social Services of Wisconsin and Upper Michigan (LSS). Under Colón’s visionary and innovative leadership, LSS has adapted new models and business strategies to increase relevancy and operational efficiency. Before the start of Colón’s tenure in 2017, the organization had not met its budget for four consecutive years. Since that time, LSS has experienced a $17.4 million dollar turnaround. He recently was named the Nonprofit Executive of the Year by BizTimes Media and the Hispanic Man of the year by UMOS. He is the host of LSS’ first podcast, “In the Ring with Héctor Colón”, released on March 16, 2022.

As Executive Director of the Milwaukee County Department of Health and Human Services, Colón led several countywide initiatives, including efforts to reform the juvenile justice system, end chronic homelessness, transform mental health care, and end a 30-year waitlist for disability services.

Héctor will say that his own personal and professional turnaround began in boxing. As a member and champion of the national USA Boxing team, he won seven national titles and competed in the 1992 Olympic trials. At the height of his boxing career, Colón stepped away from a lucrative boxing career to serve God. Today, he is the USA Boxing Board Vice President where he and the organization focus on inspiring athletes to discover their own path towards personal and professional greatness. He also serves on the University of Wisconsin Board of Regents, and the Board of Directors for M3 Insurance, as well as Nicolet Bankshares, Inc. (NASDAQ; NCBS), the holding company for Nicolet National Bank.
