In Loving Memory of Dan Callahan

A Life of Service, Family, and Community

For over 35 years, Dan Callahan proudly called Bartlett, Illinois home. As the founder of Dan Callahan Plumbing & Irrigation, he dedicated more than three decades to serving the local community with honesty, integrity, and a tireless work ethic. Alongside his beloved wife Martha—his partner in life and business for 37 wonderful years—Dan built a small, family-owned company rooted in trust and personal connection.

A devoted father of three, Dan balanced the demands of running a business with his unwavering commitment to his family. He believed in doing things the right way, treating customers like neighbors, and giving back to the town he loved.

Though Dan is no longer with us, his spirit lives on in every service call, every satisfied customer, and every project completed with care. We are proud to carry on his legacy—growing the business he started, serving the Bartlett community he cherished, and honoring the values he instilled in us.

Thank you for supporting us as we continue Dan’s mission: dependable service with a personal touch.
