Our Vision, Values, and Mission

Our History

U.S. Micro-Solutions, Inc. is a full-service Environmental Microbiology Laboratory located in Latrobe, PA. Founded in 1995 and incorporated in 1996 by Herbert Layman, BS, SM, CIEC, the laboratory was initially housed in a small space in Jeannette, PA and then in Greensburg, PA. The business has grown over the years, requiring a move to our current location at 302 Unity Plaza in Latrobe, PA.

In 2017, Herb’s daughter, Deanna Kiska, Ph.D., became president of the company. Herb has retired but continues to serve as an independent consultant which allows him to use his 50+ years of microbiology experience to benefit our customers.

We look forward to a bright future as a family-owned business who cares about our customers, our employees, and our community.
