Family Laboratory Goes to Pot : GreenHill Laboratory, LLC

Hilary Glass’ family has a history of interesting and creative jobs. Her father is a professor of ethical theory, logic and epistemology at the University of Wisconsin-Lacrosse, and her mother is a microbiologist and owner of Leuther Laboratories, LLC a food, water, and environmental microbiological laboratory 40 yrs. in business. Her sister, Dr. Tiffany Glass is a molecular biologist married to Dr. Susanta Hui, a Radiation Physicist, and her brother, Edward Glass is a medical laboratory scientist. Step father Dr. Donald Salter, GreenHill Laboratories, LLC director is a geneticist currently focused on plant genetics.

Hilary grew up working in the rural Wisconsin laboratory, and navigated to Colorado supporting herself as a visual artist and musician.


Together with her friend Jessica Olson, also with a laboratory background, and attorney Richard Ivker, the trio opened Greenhill Laboratories in Carbondale, Colorado, one of only three licensed labs certified for microbial testing in Colorado giving the team the opportunity to be the lab of choice not only on the western slope (think of the treacherous winter roads portrayed in the snowbound hotel in The Shining) of Colorado, but also in the eastern slope region, metropolitan Denver, and the Colorado Springs area, all of which are a reasonable drive in the less inclement times of the year.

A specialty that sets Greenhill Laboratories apart from the other licensed laboratories in the state is that they were founded by microbiologists; most of the other laboratories in the state were founded by chemists. GreenHill’s chemistry division is currently gaining speed as director of analytical chemistry Ryan Randolph has come on board. The lab prides themselves on their ability to do analyses of cannabis and cannabis products utilizing classic microbiology methods as well as latest technologies when they are the most appropriate for a specific cannabis product. There focus is accuracy, confidentiality, customer understanding and utilization of test results applied to production processes.

After a year of build out, documentation, and review, GreenHill received its certification on March 24; validation for potency and homogeneity testing is pending. Their lab can handle up to 3,000 samples per day for analysis. The lab is also working on validation requirements so they can receive their certification to perform residual solvents testing and homogeneity testing (consistency of potency in processed goods), and expects to become certified to test for or toxins, chemicals, and pesticides.

Colorado’s Marijuana Enforcement Division (MED) has done a pretty good job of separating church (lab testing services) and state (, producer, processing or retail licensee owners) by prohibiting the PPR’s from having a financial Interest in any licensed lab testing company. However, that has not stopped the PPR’s from lobbying heavily to delay the enforcement of microbial testing requirement that is still not mandatory even though it was slated to be as of October 2014.

In addition to the founding members, Hilary’s team is comprised of industry veterans.

Additional Greenhill Lab Team Bios

Senior Consultant Mary Leuther, has a Bachelor of Science from Florida State University, and is the owner of Leuther Laboratories, LLC has over 40 years of experience in microbiological and chemical analysis of food (dairy, raw and processed meat, vegetables, fruits, nuts, animal feeds, herbs, honey, juices, and gluten products), environmental (plant equipment, floors, walls, processing), environmental waters (potable, irrigation, surface and waste waters) and inspections and identification of environmental sampling points in food production and storage facilities. She is a member of the American Chemical Society, American Society for Microbiology, and American Society of Clinical Pathology, as well as a National Registry Microbiologist in Pathogenic Bacteriology and Mycology.

Laboratory Director Dr. Donald Salter has a Bachelor of Science in Bacteriology from the University of Alabama, an MS in Bacteriology from the University of Florida and a Ph.D in Biomedical Sciences from the University of Tennessee. Prior to obtaining his Ph.D, Salter was the military head of the Microbiology, Mycology, and Mycobacteriology Sections in the Department of Pathology at Valley Forge General Hospital in Pennsylvania during the Vietnam War. He has done post- doctoral research in cancer biology and membrane biochemistry in the Department of Microbiology and Biochemistry at the University of Illinois, and immunology in the Department of Microbiology at Michigan State University.

As a research microbiologist in the USDA-ARS Avian Disease and Oncology Laboratory in East Lansing, and then research assistant professor and consultant in the Department of Microbiology at Michigan State University, he was the lead researcher of a team that produced the first transgenic chicken as well as the first transgenic disease-resistant animal. He received a National Science Foundation Research Opportunity Award to do research in plant molecular and cell biology in the Department of Plant Biology at the University of Wisconsin in Madison in summer of 2004 and 2005. He retired in 2006 after a decade of teaching microbiology (nursing and general), biology, cell biology, genetics, biochemistry, virology, undergraduate and graduate research, seminar, and associated laboratories in the Department of Biological and Environmental Sciences at the University of West Alabama. He has been a consultant in Leuther Laboratories since 2002, and has worked over five years as a molecular biologist (half-time) in a small seed company.

Greenhill recently hired Ryan Randolph to lead their development of the analytical chemistry platform. He brings a wealth of experience to the team as well;

  • 14 years of experience in analytical method development and validation in both EPA and FDA regulated environments testing agricultural crops and animal bloods.
  • Five years spent developing and validating methods for determination of pesticide residues in agricultural crops to support EPA registration studies
  • Nine years dedicated to studying how pharmaceutical compounds are absorbed, distributed and eliminated from the body.

Greenhill Labs seems to have the talent, skills and location to be a key part of the Colorado lab testing community. And they seem to have a strong vision and visionary that should translate into success.


As an artist, Hillary tends to take on large abstract projects and enjoys the challenge of bringing out her innate feelings dealing with concepts like government freedom, religion, music or other philosophical ideas that bring out her original style. Greenhill Labs hopes it original family roots in microbial testing and solid science add up to a lot of greenbacks in 2015 and beyond.
