The Salt Lake law firms of Parsons, Behle & Latimer and Biele, Haslam & Hatch have agreed to merge.

Effective June 1, the firm Biele, Haslam & Hatch will dissolve, as 11 of its 12 lawyers join Parsons, Behle & Latimer, a spokesman said. Co-founder Irving H. Biele will continue a private practice and not move to Parsons, Behle.Biele, Haslam was founded in 1974, serving the financial industry with clients such as Valley Bank & Trust Co., Valley Mortgage Corp., Great Western Thrift & Loan and other financial institutions.

"Our expertise in the area of banking law will nicely complement the already strong practice of Parsons in the areas of litigation and natural resources," said managing partner Roy Haslam.

He said that growing client needs was the main reason he and other partners considered joining a larger firm.

Founded in 1882, Parsons, Behle has a long tradition in mining and natural resources law and employs about 150 in representing clients in all areas of law. This most recent announcement and several "lateral hires" is part of Parsons, Behle's ongoing effort to expand its growing services, said F. Robert Reeder, who handled the merger with Biele, Haslam.

With the recent additions, Parsons, Behle will have more than 80 lawyers. The firm maintains offices at 185 S. State and 50 W. Broadway, but will consolidate into one location in 1991, the spokesman said.
