Who We Are

Lynn Bartholow, CEO/Founder

Having personally witnessed the benefits people have gained from participating in clinical research, I have a profound belief that everyone should have the opportunity to be involved in a clinical trial. Participation can also provide individuals with a sense of empowerment and agency over their own health and wellbeing. I founded Circle Clinical Research because I’ve seen first-hand the impact of clinical research.

Guided by my core values of courage and trust, I want to create a welcoming, inclusive space for all. I am an enrolled tribal member of the Turtle Mountain Band of Chippewa Indians and believe in the Seven Generation Principle. The Seven Generation Principle is an Indigenous Concept, to think of the 7th generation coming after you in your words, work and actions, and to remember the seventh generation who came before you. Seven generations ago, an Assiniboine woman named Red Nest was born in 1818, my great, great, great, great grandmother. I want to honor and remember her through my work. Based on this seven generation principle, I feel obligated to serve past, present, and future generations. I want to fulfill this obligation by using the skills and knowledge I’ve acquired with my 20+ years of involvement in clinical trials.
