Our Story

Phyllis Sordelet purchased S & K Reagents in January 1988. The company remained in Washington Park with its eclectic host of neighbors. Most customers were met by the company dog, Gracie who liked to lie outside the front door. The name was changed to Rocky Mountain Reagents (RMR) in October 1996 as the company expanded its services. RMR acquired another space in the same block to accommodate the expanded product line which included titration reagents, indicators, chemical test solutions for industrial applications and custom reagent manufacturing.
Later that same year, the company was moved to a 2,500 square foot space in Sheridan Colorado. In 2001, RMR purchased First Service Supply Company. With this acquisition, RMR was able to offer its customers a wide variety of acids, bases, solvents and chemicals in ACS, Semiconductor, USP, FCC, Technical or Commercial grades. Over the next ten years, Rocky Mountain Reagents continued to take more space.


In 2006, plans were made to build a new building in Golden Colorado. Over the course of a year, the building was constructed and RMR moved to its' 20,000 square feet, state of the art building in April of 2008. The company now serves a diverse customer base throughout the Rocky Mountain region as well as all 50 states.
