Anton Collins Mitchell LLP (ACM) is pleased to announce a new office in Laramie, Wyoming. The accounting firm of Mader Tschacher Peterson and Co, LLC (MTP&C) has combined their practice with ACM effective January 1, 2016.

“Expanding beyond the Front Range into Wyoming is a significant strategic step in providing full service accounting services to the Rocky Mountain region.” says President and Managing Partner, Stacey Hekkert. “Our firms share a deep commitment to how we approach client relations, have complimentary industry practices and have a culture that is focused on personal development and individual success. MTP&C is a well-respected, dominant firm and we are proud to have them join ACM.”

Hekkert advises that the firm continues to be in growth mode. This is not the first merger for ACM in the past five years. ACM merged in a practice in Greeley, Colorado in 2010 and a Boulder practice in 2012.

The staff in the Laramie office remains the same and will continue to be led by Mark Mader, Dennis Tschacher and Rolf Peterson and newly admitted partner, Steve Blundell. The firm’s 35 year commitment to provide independent, objective and comprehensive business solutions remains intact.
