Approximately 180 team members give back through annual Maner Cares Day of Impact 

GRAND RAPIDS, Mich. – With the holiday season approaching, Maner Costerisan team members got an early start on the season of giving, trading their regular workday for a day of community service Thursday, Nov. 5, to support organizations addressing needs ranging from food insecurity and housing to animal welfare and environmental stewardship. 

As part of the accounting and business consulting firm’s ninth annual Maner Cares Day of Impact, approximately 180 team members volunteered to support 15 nonprofit organizations in the Grand Rapids and Lansing areas, with additional projects in communities across the country. 

The annual event marked the first Day of Impact since Grand Rapids-based Baker Holtz joined Maner Costerisan through a merger in January 2026, bringing together two firms with a shared commitment to serving their communities. 

In Grand Rapids, team members supported six nonprofit organizations through hands-on projects. At Meals on Wheels Western Michigan, volunteers helped portion, plate, seal and label hundreds of home-delivered meals for area seniors. 

“We are so grateful to the team from Maner Costerisan for volunteering at Meals on Wheels Western Michigan as part of its Day of Impact,” said Lisa Wideman, president and CEO of Meals on Wheels Western Michigan. “They did a great job plating over 1,200 Salisbury steak meals. This is a huge help for our kitchen team, which produces 2,000-5,000 meals every day. Thank you for helping to ensure that no senior is hungry or forgotten.” 

Other projects included assisting with construction and improvement work at Habitat for Humanity of Kent County, completing cleaning and animal enrichment activities at Kent County Animal Shelter, and planting trees with Friends of Grand Rapids Parks. 

“Maner Cares Day of Impact is a great reflection of the role we can play in supporting the communities where we live and work,” said Melissa Seguin, CPA, principal at Maner Costerisan.  

“Being part of the planning process this year made it especially rewarding to see our team members come together and support organizations that are making a real difference throughout West Michigan. It’s important that we continue building these connections and finding meaningful ways to give back.” 

Team members also assisted with various projects at Gilda’s Club Grand Rapids and helped control invasive plant species, including bittersweet vine, along trails at Seidman Park through Kent County Parks. 

The Day of Impact also included projects throughout the Lansing area, as well as Traverse City and communities in several other states. 

Since launching Maner Cares Day of Impact in 2018, more than 760 volunteer participations have contributed over 3,000 hours of service to more than 70 nonprofit organizations.
