MEET OUR TEAM
FOUNDER & CEO
Greg Heiland, a recognized leader in contamination control, has dedicated himself to promoting critical environment excellence for over 30 years. After graduating from Santa Clara University in 1982, Greg launched a 6-year career with American Scientific Products in sales and management roles. In 1988, Greg and his wife, Mary, founded Sierra Scientific, an Arizona-based cleanroom products distributor. They acquired the Texas-based supplier, Class 10, and started Valutek, a controlled environment consumables manufacturer in 2000.
Known as an industry expert, Greg is a frequent contributor to contamination control publications, trade shows, and the development of cleanroom standards. For his long-term commitment to IEST, he was awarded the 2018 Robert L Mielke award. When not promoting the protection of products, people, and practices, Greg enjoys travel, the outdoors, and spending time with his family.
CO-FOUNDER & VP OF HUMAN RESOURCES
A native Californian, Mary graduated from the University of Southern California with a Bachelor of Science degree in Occupational Therapy. She began her career in neuro rehab at St. Jude Hospital in Fullerton, CA. She then worked as a pediatric OT for California Children Services in Orange County, CA and Howard County Schools in Maryland. In 1988, Mary co-founded Sierra Scientific with her husband, Greg, and subsequently Valutek in 2000.
As our internal and external “goodwill ambassador”, Mary’s role as culture advocate, team builder, talent recruiter and celebrator is the heart of Valutek. Whether planning monthly themed “team appreciation” luncheons or celebrating any and all milestones, Mary’s legacy is her genuine care for the well-being of the team and the business. In her leisure time Mary enjoys cooking, crafting, volunteering, travel and keeping connected with four grown children and their exciting lives.
