After earning a degree at the College of Southern Idaho, Colleen Jacobsen embarked on a career in medical research.  Initially focusing on family practice and dermatology, Ms. Jacobsen pivoted and quickly learned the numerous facets of operating a research facility.  She joined Advanced Clinical Research in 2014 as a CRC and later advanced to role of Site Manager.  With experience in over 20 therapeutic areas, she was an obvious choice to open additional spoke sites.  In 2019, ACR was acquired by Velocity Clinical Research and tasked her with establishing their first clinic in the Lonestar state.  After successfully navigating the challenges of the COVID era, Ms. Jacobsen returned to her home state and became Site Director for the Boise clinic.

Laura Crenshaw earned her BA in Mass Communication and Journalism, with a Minor in Marketing from Boise State University.  Needing a full-time job in the mass economic recession of 2008 she agreed to come work as a patient recruiter for clinical research, knowing nothing of the industry, but eager and willing to use her “gift of gab” to help market Advanced Clinical Research in the community.  Not knowing the full career path and opportunities that lie ahead she spent 5 years recruiting patients into hundreds of vaccine and chronic studies, then moved into adhering to FDA regulations for the site as a Regulatory Specialist for another 5 years.  With her in-depth knowledge of the industry and having worked 10 years for the company she advanced to Business Development to help continue building connections with sponsors and CRO’s to bring new therapeutic areas to the site.  After successfully navigating these areas of research she became the Site Operations Manager in April 2021 under Velocity Clinical Research.  Laura loves helping problem solve and tackle day-to-day operations to help drive Velocity’s success.
