Core Values and Guiding Principles

Integrity – In everything we do: we keep our promises, walk the talk, and always do the right thing.

Passion for the Customer

We value our customers as the lifeblood of our business. Our relentless pursuit: to build stronger working relationships, to understand our customers’ needs and to help them succeed in their business objectives.


Success for M&M requires every member of the team, and all members are equally important, regardless of the position they play.

Empowered Employees

Driven by a clear sense of our purpose and values, each member of our team is entrusted with the use of resources and decision-making in their individual area of accountability.

Commitment to Excellence

In everything we do, we are committed to delivering the highest level of quality: in what we create and in how we perform.


Our business is built on relationships that grow – internally with M&M employees, and externally with customers and our suppliers.


Each of us is responsible for the health, care, growth, feeding and profit in our roles in our respective areas of the business…even if it means we are only in charge of ourselves and our decisions.
