The California Team

The dedicated staff in the California office.

C.R. (Gus) Manning, PhD, CIH, Founder and CEO

Since Assay’s inception in 1981, Gus has focused on developing Assay’s personal monitoring badges, and supporting them with business strategies. After 2004, with the acquisition of the Miller-Nelson Atmosphere Generator and Respirator Lab, he also had to get his technical director mind around respirators. Currently, he worries about growth and development while a lively and intelligent staff handles most day-to-day activities, allowing him to play baseball and dream. gmanning@assaytech.com

Steve Green, B.S in Chemistry, Chief Operating Officer, Director of Laboratories

Steve earned his degree from Santa Clara University in 1989. and joined Assay in 1999.  He oversees all aspects of Assay Technology’s two accredited IH laboratories. He was recently promoted to general manager to oversee most operations at Assay Technology. He has played shortstop on the company team for the last 22 years. He is known to be a dead-pull hitter who feasts on right fielders who can’t track his shallow pop flies. He is frequently found taking pictures of nature during walks, telling passers-by, “Nature is billions of miracles happening all at once.” sgreen@assaytech.com

Karina Abreckov, B.S., CFO

Karina manages and controls all of Assay’s financial activities, including budgeting and projections. She is at the tail end of becoming a CPA. At home, she enjoys spending time with her family and friends, cooking, and making lifelong friendships. kabreckov@assaytech.com

Terry Yeung, B.S., Director IT & Lab Systems

Terry joined Assay in 1993 as a lab chemist, then a lab supervisor until 1999, at which time he had an epiphany, which led him to become Assay’s information technology guru. As a scientist with IT know-how, he bridges the gap between computer systems, lab instruments, and data; helping us to achieve a good integration of company systems.  His experience and inclinations have also imbued him with a wealth of knowledge about almost everything, both trivia and important stuff. tyeung@assaytech.com

Kathy L. Taylor, B.S., Laboratory Manager (Ohio)

Kathy was working at DeYor Laboratory when it was acquired by Assay in 1997.   Subsequently, she became AT Labs’ Ohio lab manager, presiding over the GC analysis of organic vapors, metal spectroscopy, HPLC, IC, wet chemistry, dust . . . you name it. Kathy hails from Rio Grande (the one in Ohio), and is one of the main reasons the lab delivers 99% of its reports on time.  Kathy is a retired die-hard hockey Mom who loves to knit and read.  Her secret passion is horses and horseback riding. ktaylor@assaytech.com

Beth Green, B.S., Marketing & Customer Support Manager

Beth is the kind of person who loves to line through items on a To Do list, and never tires of completing tasks to improve the health of the business and the happiness of our customers. She is responsible for marketing and customer service, including advertising, branding, and business development. An employee since 1996, Beth is from TN, the Volunteer State, and spends time volunteering as team manager for her daughter’s synchronized ice skating team.  Beth enjoys baking, TV shows about baking, and reading books (some about baking).  When not baking, you might see her swimming laps at the community pool, or walking around the local sports park. bgreen@assaytech.com

Maria Peralta, PhD, Technical Director

Maria provides technical development, solutions, support and guidance to Assay and its customers across all Assay Technology products and services.  You’ll mostly come across Maria as she speed walks past you on her way to and from the lab while thinking of the next 10 things to do. She has an array of experience from thin film diamond synthesis to recombinant protein expression. When not thinking of science, she enjoys cooking and the company of family and friends. mperalta@assaytech.com

Jorge Gradillo, B.S., Manufacturing Supervisor

Jorge joined Assay in 2000, and currently oversees the purchasing of materials, production planning, and final assembly of products.

Kim Chen, M.S., Human Resources & Facilities Manager

Kim joined Assay in 2010, but she has been managing people all her life. She is the youngest of 7 siblings, so juggling personalities is second nature to her. In her spare time, she enjoys spending time with her family, following local sports teams, and traveling around the great state of California and beyond. kchen@assaytech.com
