BerryDunn Principals Recognized by Forbes Magazine as Top CPAs in America


This inaugural list of the top 200 prominent practicing CPAs in America was compiled by the magazine’s editorial staff based on nominations.

BerryDunn, a full-service assurance, tax, and consulting firm, announces the recognition of two Principals—Tammy Michaud, CPA, and Dave Erb, CPA—making the Forbes inaugural list of America’s Top 200 CPAs 2024. According to Forbes, more than 1,000 candidates were evaluated and graded on the following criteria: certifications and credentials, years of experience, industry specialization, professional achievements, community involvement, thought leadership, client base and diversity, ethical and regulatory compliance, and innovation and technology adoption.

In addition to the significant impact of their work, both Michaud and Erb have received many accolades from CPA societies and associations during their careers to achieve this recognition. Michaud, whose career spans nearly 40 years, is Chair of the Board of Directors, leads BerryDunn’s Not-for-Profit Practice Group, and is co-leader of BerryDunn’s nationally recognized Home Health and Hospice Practice, partnering with healthcare and nonprofit organizations to effect lasting change and innovation.

“I am honored to be included in this list with Dave and other prominent CPAs,” says Michaud. “I have been fortunate to work alongside exceptional colleagues at BerryDunn, contributing to important strategic initiatives like the firm’s merger with a regional home health accounting firm. I’m proud of our commitment to leadership in our industries.”

Erb, whose career spans 33 years, has experience in strategic management of federal and multistate tax planning and leads BerryDunn’s growing Tax Compliance and Consulting Practice Group. “What an honor to be included on the list with other CPAs nationwide,” says Erb. “Growing and developing teams here at BerryDunn has been rewarding, knowing that maximizing professional development opportunities and focusing on client service can bring lasting results.”

This recognition of Michaud and Erb epitomizes the three pillars at BerryDunn—people, expertise, and innovation: a people-oriented culture, deep expertise in 30+ industries, and innovative problem-solving. “Tammy and Dave are trailblazers when it comes to innovation and community impact,” says Renee Bishop, COO. “Tammy, who was a 2022 New Hampshire Business Review Top 200 most influential business leader, is a mentor and staunch advocate for women balancing workplace success and family and chairs the firm's Board of Directors.  Dave is a model of excellence with his commitment to the accounting profession and community, serving as a delegate for the STAR group and representative at AICPA Major Firm Group meetings.”
