The History of M&M Plumbing Heating Cooling
From a single operation to a trusted name across three counties, we've built something that lasts. The work speaks for itself.
1957
The beginning
M&M Plumbing, Heating & Cooling was founded in Indian River with just one truck and two employees. The early days were simple. A rented building, an oil stove for heat, and a commitment to serving the local community.

1960s - 1990s
Building a Reputation
The company steadily grew as more homeowners and businesses trusted M&M for dependable service. New employees joined the team, more trucks were added, and the foundation of long-term customer relationships was built.

2007
Passing to the Next Generation
Ownership of the company was passed to Scott, continuing the family legacy. The values established in the early years remained the same, with a focus on honest work, strong relationships, and reliable service.

Our History & Full Story
M&M Plumbing, Heating & Cooling has been part of the Indian River community for over 65 years.
What started with one truck and two employees has grown into a trusted team serving homes and businesses across Northern Michigan.
A Family Business Built on Hard Work
Our story begins in the 1950s.
- Dick began his career with a plumbing and heating apprenticeship in Flint
- He and his wife met in 1954 and married the following year
- They returned to Indian River with just $600 and a vision for something more
In the early years:
- The business operated out of a rented building on Sturgeon Street
- Heat came from a single oil stove during long Michigan winters
- Locals would stop in for coffee and conversation around that stove
Those moments shaped the culture you still experience today.
Growing With the Community
M&M was built step by step:
- Started with 2 employees and 1 truck
- Expanded services and added equipment over time
- Built lasting relationships with local homeowners and businesses
The company name comes from a partnership between Dick and his nephew Monte, reflecting the family roots that still define the business.
Passing It to the Next Generation
- Ownership transitioned to Scott in 2007
- Dick remained involved until his passing in 2008
- The same values of honesty, hard work, and service continue today
Built for the Future
