Rick Cox, Chief Operating Officer


Tyler Doerksen, KS Plains Technical Specialist

I have 10+ years of experience in a variety of molecular and microbiological labs including plant pathology research,
pathogen diagnostics, and food safety. My roles have included training lead, quality manager, and head of special
projects.

Tanedjeu Kemgang, PA Northeast Technical Specialist

Originally from Cameroon in Central Africa, I spent the last 10 years working as a researcher and scientist for
company startups and universities in areas like food sciences, immunology and molecular biology, to cite few. In
2022, while working as a lab manager, I met with the pipette lady and I decided to join the team. Since then, I have
been in charge in the great area of the Northeast including PA, NY, NJ, DE and assist with the surrounding
territories. Outside of work, I am a loving father of 3 boys who enjoy long travel by car throughout the country.
Being a part of the Calibrations International team has given me the opportunity to explore many states, from
north to south, while providing excellent service to our clients. I also play soccer and volleyball from time to time to
stay fit and workout.

Jesse & Araceli Espinoza, IA Midwest Technical Specialists

Jesse is the lead for our husband & wife Iowa Midwest Team. Formerly a Clinical Research Laboratory Manager at
the University of Iowa, he has extensive experience with laboratory equipment, testing, protocols and regulatory
documentation. We provide “top gun” service in Iowa, Missouri, Illinois, Indiana and Kentucky, as well as the
surrounding areas, giving you professional courteous service.
