Meet the Team

Theresa L Rohe, President & Chief Executive Officer

Blessed to have the perfect blend of education and training in business management and the nutritional sciences, Calibrations International has been a beautiful evolution for me.  I started as a technician for a Florida based company where I received my initial training.  We developed a partnership for our ISO 17025 company, USA Calibrations, and simultaneously Calibrations International was born.  Determined to travel and apply my love of science, I hit the ground and started in Pennsylvania developing the I-70 territory between my home state of PA and beautiful Colorado.  In 2018, we moved the company west to Bozeman Montana providing service to 34 states at that time. As we continue to grow, we now serve 45 states and have been blessed to work alongside some of our great clients that have joined our team.  

Theresa started Calibrations International over 17 years ago after being a partner of USA Calibrations, an ISO 17025 company. Theresa and Rick now serve over 45 states with both on site and administrative duties. Rick joined full time in 2020 after over 7 years in occupational therapy.

Outside of work, Tanedjeu is a loving father of 3 boys who enjoys road trips, soccer, and volleyball.
