Karen Kelleher

Founder & President
About

I have been in the Wellness Industry for almost 25 years, and created Boston Thermography Center Inc. in 2012. Prior to entering the wellness field, I was in the technology industry employed by Sun Microsystems for 14 years. I was a Material Analyst responsible for materials and supplier management. I was promoted to Materials Platform Manager responsible for the global materials team supporting new product development. In my last position I was in marketing as a Product Manager/Forecast Specialist. In this role, I was as a field liaison for customer activities, product road maps, target markets, and quarterly pricing recommendations.

I became interested in Thermography with the loss of my dear friend Laurie to Breast Cancer. I hope to help educate others in the value of thermography as a complementary tool in detecting changes in breast health.

Education

I have earned a Bachelor of Science in Business Administration from Eastern Nazarene College, and a Bachelor in Holistic Health Sciences from Quantum University. I have my Master of Science degree in Natural Health, graduating with honors from Clayton College. I am also pursuing a PhD in Natural Medicine from Quantum University.
