Dale L. Rindlisbacher and Roger Sorenson, who are brothers-in-law, probably still would be teaching music in public schools today had it not been for the desire to support their sons on missions for The Church of Jesus Christ of Latter-day Saints.

They dabbled in the construction business while teaching music for several years. In 1976 Rindlisbacher formed Bach Builders and since has expanded to three other companies, Bach Development Co., Bach Realty and Bach Investments.Rindlisbacher, with eight children, and Sorenson, who has seven children, decided they could better support their families by being in the housing business, and the decision apparently was a smart one. They have developed 18 subdivisions and have built several hundred homes in the Salt Lake and Davis County areas.

They are in the process of developing 172 lots at several locations, and this summer they will start on another 236 lots in the same areas. They have 57 lots under development in Regency Place 1 and 2 in South Jordan; 36 lots in Quail Brook in South Jordan; 42 at Cottonwood Place in Sandy; 27 at Eagle's Landing in Bountiful; and 10 lots in The Woods in West Jordan.

The two men also are in the process of purchasing an additional 25-30 acres of raw land in South Jordan, which they plan to develop after completing their current projects.

In the past 41/2 years, Sorenson said, the Bach corporations have done well, and it's gratifying to see the subcontractors keep busy so they can support their families in spite of some tough times in the construction business elsewhere.

As Rindlisbacher, who is president, and Sorenson, who is vice president, develop their land, houses either are built by Bach Builders or the lots are sold to individuals or contractors. They try to develop a subdivision with houses having a minimum of 1,250 square feet next to a subdivision with homes containing a minimum of 1,600 square feet so people can pick one that best fits their budget.

Their aim is to have houses that don't all look alike, and they also like a parklike appearance so they plant trees and grass in the parking strip. The subdivisions in South Jordan and Bountiful have piped irrigation systems.

The booming housing business in West Jordan and South Jordan is a far cry from when Rindlisbacher built in the 1970s what he calls "tract" houses in Kearns, West Valley City and Taylorsville. Only the colors were different on the houses, Rindlisbacher said, and the average cost was $42,000.

Since then, he has built everything from entry-level to a $400,000 house. Rindlisbacher said many people are unaware of the large expensive houses being built on the southwest side of Salt Lake Valley for professional people.

Raised in Riverton, Rindlisbacher received bachelor's and master's degrees in music from the University of Utah and worked toward a doctoral degree from Brigham Young University. He taught music for 10 years, the last four at Cottonwood High School.

While he was teaching, he built his own home and worked on other houses as time permitted. He formed Bach Builders in 1976 and incorporated with his brother, Jay Rindlisbacher, in 1979. They ex-panded to form Bach Development to develop raw land into residential building lots.

Sorenson was born in Salt Lake City, raised in Magna, received a bachelor's degree in music from the U. and has worked toward a master's degree. Rindlisbacher's father was Sorenson's band teacher. After Dale got acquainted with Sorenson, he introduced him to his sister and they later were married.

The two men taught school together at Granger High School in 1972-73, and Sorenson also taughtseminary for the LDS Church. He obtained a contractor's license and built several homes while he was still teaching but 41/2 years ago quit teaching and started with Bach.

Bach has six employees, including supervisor Tony Christensen, who oversees the work of the subcontractors. As part of the company's office at 9235 S. Redwood Road, a display area is available where customers can pick all of the items that will be included in their houses such as shingles, tile, carpet, cabinets, countertops, exterior siding, linoleum and brick or rock.

Big in the housing business these days, according to the two men, are windows of every size and shape, double and triple garages, large bathrooms and spa bathtubs.

"It's an exciting business," they said, looking over one of their partially completed subdivisions.
