Social Responsibility

A positive impact on our community - and on the world.

Stronger communities start with social responsibility

Since our firm was founded, Tonneson + Co has had a long, proud history of giving back to our community and helping those in need. We reward all employees who bring forward a cause they are passionate about by granting them paid time off for volunteering. By promoting these positive efforts from our employees, we create a more productive and positive work environment and contribute to a better world.

Days of Service

Every year, our employees participate in the MassCPAs Day of Service. We choose a cause that is important to us and take time out of the office to focus on giving back.

Here are just some of the ways we have volunteered in the past:

  • Assisted with trail clean-up for the Appalachian Mountain Club
  • Painted a house for of the residences with Communitas
  • Worked and donated food for the Merrimack Valley Food Bank
  • Donated masks and PPE supplies to local first responders
  • Managed donations at the Cradles to Crayons Giving Factory
  • Sorted donations at the Catie's Closet Distribution Warehouse


Lending a hand to our non-profit partners

We have ongoing relationships with many charitable organizations, including Catie’s Closet and Merrimack Valley Food Bank, which we support with annual contributions, pro bono work, and volunteering.

“Tonneson + Co never ceases to amaze me. In addition to providing expert financial services, they are committed to making our community a better place. They are the first to volunteer, host clothing drives, support our homeless youth, and make our outreach more impactful. Catie’s Closet is more successful as an organization because of their ongoing support.”

Impacting positive change

At Tonneson, you’re not just part of a workforce; we care about impacting positive change. Through my involvement, I’ve witnessed firsthand how a single act of kindness, a sustainable initiative, or a commitment to ethical practices can ripple outward and inspire others. I take pride in knowing that my role goes beyond the confines of a job title, making a difference and contributing to a purpose far greater than myself.

—Karianne Bekier | Audit Director
