Chicago, IL − BDO USA, LLP, one of the nation’s leading accounting and advisory firms, today announced the addition of 167 professionals from ACM LLP (formerly Anton Collins Mitchell LLP), the largest Colorado and Wyoming based public accounting firm headquartered in Denver. ACM has been a member of the BDO Alliance since 2002, prior to that the firm was a part of BDO. The combination is subject to customary closing conditions and is expected to be completed on August 1.
“As a BDO Alliance USA firm, BDO and ACM have an intertwined history dating back nearly 20 years,” said Wayne Berson, CEO of BDO USA. “In officially welcoming back ACM partners and professionals to BDO, we expand our resources in the Rocky Mountain region and open up opportunities for our people to thrive. From industry focus to market-facing strategy to advanced technical attention, BDO and ACM bring incredible insight and industry-leading creativity to our work. Our common commitment to prioritizing exceptional client service and supporting our people will ensure a seamless transition for clients in the weeks and months ahead.”
Founded in 2002 with offices in Denver, Northern Colorado, Boulder, as well as Laramie, WY, ACM provides assurance, tax and consulting services to companies ranging in size from start-up organizations in the development or exploratory stage to established entities with multi-state and international operations. ACM is known for industry, professional and community leadership and has been frequently recognized as a Fastest Growing Private Company, a Best Company to work for and a Best Accounting Firm to work for. 
“ACM and BDO have had a very strong relationship and worked closely together for many years, and reuniting is a natural next step on the path we’ve built together,” said Gregory J. Anton, chairman and CEO of ACM. “At our core, ACM is a people, client and community-focused organization, so it was imperative that we combine with a firm grounded in those values — and is why we chose to continue to grow our Rocky Mountain footprint with BDO. What makes this combination unique is bringing the touch of the largest locally owned firm together with the fifth largest firm in the world.  The resources we will be able to bring to clients in the region is unmatched.”
The BDO and ACM combination is a homecoming for Anton, who spent the first 15 years of his career at BDO before cofounding ACM. He is also a past chairman of the American Institute of CPAs (AICPA), the world’s largest member organization representing the CPA profession. At BDO, Anton’s leadership will bolster the firm’s geographic presence and drive growth in the Rocky Mountain market.
“The combination of BDO and ACM is a natural fit given the firms’ shared histories and complementary cultures,” said Stacey Duke, president and managing partner of ACM. “ACM was already a part of the BDO family – we’ve just made it official. The combination of the two firms demonstrates BDO’s commitment to expanding its footprint in the region, and to uncovering strategic opportunities in both familiar and brand-new territories.”
BDO will maintain ACM’s four existing offices in Denver, Northern Colorado, Boulder and Laramie.
