A new Newport Beach-based commercial real estate brokerage and management company called Tiarna Real Estate Services Inc. will soon be opening a San Francisco office as it spreads to become a regional player.

Formed by three veteran brokers and property managers from Charles Dunn Co. and one from Trammel Crow Co., the company currently has offices in Newport Beach, Encino and Scottsdale, Ariz., and expects to open a San Francisco office soon.

Tiarna’s president is Thomas McAndrews, a former president of real estate management services at Charles Dunn Co. His partners in the venture are Scott Alleborn and Robert Deaton, both former regional managers with Dunn, and James Bannan, a former Trammell Crow Co. vice president. Alleborn is the company’s executive vice president, Deaton is executive vice president of its Arizona operations, and Bannan is executive vice president for brokerage.

Tiarna, a Gaelic word meaning landlord, will focus on brokerage, property management and advisory services for landlords. The business is hoping to get business from owners of real estate who are fed up with consolidation in the industry, and wish to deal with the principals of a smaller firm rather than the employees or a larger firm.

Tiarna has opened its doors with leasing and management contracts for 2 million sf of office and industrial space, including one contract with a pension fund advisor.
