US-based Coldstream Wealth Management has announced mergers with wealth management firm Seidman Capital Group and accounting and consulting services company Hersman Serles Almond.

Established in 1996, Coldstream Wealth Management is an independently operated wealth management firm that offers services to high-net-worth clients.

The fully owned subsidiary of Coldstream Holdings helps clients to navigate through the complexity of wealth management.

Through the mergers, Coldstream Wealth Management intends to boost its ongoing efforts to expand its footprint in the Pacific Northwest.

Coldstream Wealth Management managing shareholder Kevin Fitzwilson said: “Combining our firms brings us one step closer to our vision of creating a world class, independent firm of the future; one that provides multiple career path choice for our employees, and broader in-house resources for tax, trust, estate and retirement plan capabilities.”

Based in Washington, Seidman Capital Group and Hersman Serles Almond are affiliated businesses and were co-founded by Victoria Serles.

Serles said: “Merging with Coldstream comes at the ideal phase of our respective businesses.

“The firm understands how we operate, the value-add that sophisticated tax services can bring to wealth management clients and how a truly comprehensive financial services company can stand out as a destination of choice for top talent who continually seek new challenges in order to grow throughout their careers.”

Seidman Capital Group, which was founded in 2004, offers financial, investment, and insurance planning services.

The firm also provides fiduciary oversight for employer-sponsored retirement plans and asset protection strategies.

Seidman Capital Group’s five advisors and three support staffers manage over $250m in assets under management.

Hersman Serles Almond manages income taxes. It also offers a range of tax-efficient services, including trust and estate planning for high-net-worth households and succession planning and valuations for businesses.

Coldstream Wealth Management had previously announced mergers with Alaska-based LWM Wealth Management and Oregon-based Rosenbaum Financial.
