About Us

Our Approach

Although we are a newly established company, MedSource has over 21 years of managing substance abuse programs and medical reviewing drug screen results.  During these 21 years we listened to clients and decided to start a company that is proficient in processing results coupled with providing cost effective programs.  Excellent customer service and effectiveness were also key factors in developing our company.  Our focus is simplifying our client’s drug testing program by working as a team. More importantly, integrity and honesty are our foundation.
