It has been a busy week or so on the acquisition front for Denver-based registered investment advisor Mercer Advisors Inc., which on Monday announced the acquisition of Sigma Investment Management Co., a Portland, Ore., firm that serves high-net-worth clients throughout the Pacific Northwest.

This comes a week after Mercer Advisors expanded its East Coast presence with its purchase of Beacon Wealth Management, which has offices in New Jersey and Florida.

Regarding Sigma, that firm has roughly 270 clients and more than $500 million in assets under management in Oregon and surrounding states. Its addition to the fold expands Mercer Advisors’ West Coast presence that includes an office in Seattle and seven offices in California.

Mercer Advisors, an investment management, financial planning and family office firm, now has more than 30 branch offices in the U.S. and nearly $14 billion in AUM. In a press release, Mercer Advisors’ vice chairman David Barton praised Sigma’s “investment management acumen.” He also noted that other companies wanted to partner with Sigma, but that his firm won the prize because its family office business model is complementary to Sigma’s investment management platform.
