Adam Karcz is a husband to a passionate special education teacher and a father of two boys, ages 5 and 2—living the same life as many of the families he serves. He is the Founder and Owner of Mammoth Mortgage, where Team Mammoth is building a new standard for how families move into their next home. In 2025, the team ranked as the #1 broker loan officer in Wisconsin for households served.

Team Mammoth was built for people in the heart of their careers, needing a process that actually fits real life. Instead of a slow, confusing mortgage experience, the team is known for delivering “speed to certainty” a clear, structured path from “we think we’re ready” to “we know exactly what to do next.”

More than a mortgage team, Team Mammoth operates as a philosophy: eliminate guesswork, move with intention, and make confident decisions backed by strategy. The mission is simple.  Raise the standard for how families experience one of the biggest financial moves of their lives.
