Virginia-based registered investment advisor Washington Wealth Management has added California Wealth Transitions and Overlake Partners to its advisor platform - a move which takes its assets under management to $1 billion.

Upon completion of the transition, the firm said its AuM will have increased from $100 million in December 2011 to $1 billion.

Based outside Seattle in Bellevue, WA, Overlake Partners is an independent financial advisory practice led by John Wilbourne, principal. Wilbourne has over 18 years of industry experience and was most recently with Wells Fargo Advisors.

California Wealth Transitions is headquartered in San Diego, CA, and is led by Keith Brandt, president. Brandt was previously at Merrill Lynch and has nearly 30 years of industry experience.

In September, WWM brought in the Domari Wealth Management team from Wells Fargo, bringing with it $135 million in AuM and $1.4 million in revenue. Brian Danelian leads the team, which is also made up of J Allen Thompson and Christine Fountain. They are based in Washington Wealth's Woodland Hills office in Los Angeles, CA.

WWM has offices in San Diego and Los Angeles, CA; Las Vegas, NV; Seattle, WA; Westport, CT; Middelburg, VA; and Miami, FL.
