RubinBrown Advisors, a wholly owned investment advisory affiliate of RubinBrown LLP, and one of Kansas City, Mo.’s largest accounting firms, has merged with Wealth Management Advisors Inc., also based in Kansas City, according to a joint release from the companies.

The combination of the two firms will operate as RubinBrown Advisors and maintain its office location in Leawood, Kan. The merger was effective May 1.

Since 1993, Wealth Management Advisors has been serving clients as a registered investment advisory firm. It serves more than 300 clients and supervises approximately $470 million of assets under management, the release said.

RubinBrown launched its subsidiary RubinBrown Advisors in 2002 to provide an integrated suite of investment advisory services and financial planning services. It has been one of the accounting firm’s fastest growing businesses with $1.23 billion in assets under management.

Kevin S. McGrew, president of Wealth Management Advisors, said his firm has received multiple offers to join others over the years, but with RubinBrown Advisors, all the boxes were checked. “I have been a client of RubinBrown for many years. Our investment and client service philosophies match up and our team is able to stay together in the same location,” he said.

RubinBrown chairman John F. Herber Jr., said the merger reflects RubinBrown’s continued commitment to growth in the investment advisory space. “The more opportunities we had to meet with Kevin and his team, the more apparent it was that this was going to be a great cultural fit,” he said.

Founded in 1952, RubinBrown, according to the release, has recently grown to be the ninth largest accounting firm in Kansas City and the nation’s 43rd largest accounting and business consulting firm.
