Our founder and CEO James Sewell moved to Southern California in December of 2014 and founded JDS Consulting Inc. starting as a one-man operation focused on Utilization Review and Consultation services. Since then, JDS Consulting Inc. has grown from that one-man operation with limited services, to the company it is today! Originally having a single client, JDS now provides services for multiple treatment facilities, doctor’s offices, laboratories and more! JDS Consulting Inc. is always growing and adapting to meet the needs of an ever-changing industry.
Originally from Omaha Nebraska, James’s midwestern roots are where he gets his strong sense of moral and ethical business practice along with his tireless work ethic that has shaped and defined every aspect and component of JDS Consulting Inc. Having worked in the behavioral health sector for several years in Nebraska, prior to coming to California. James brings a working knowledge of the entire treatment “puzzle” and how each piece needs to work for the organization to flourish. Since moving to Southern California, he has only continued to expanded his knowledge of the industry and branched out into other areas of medical billing and compliance.
James obtained his Bachelors, as well as his Masters in Counseling degrees from the University of Nebraska at Omaha. James incorporates the skills and knowledge learned through all his experiences, with his passion for helping others improve their lives. James treats all the JDS clients as if they are part of a team, rather than just another client, giving them personal and hands on time and attention.

“JDS Consulting isn’t about being the biggest, or making the most money. It’s about being the best fit and service for our clients. We don’t want 100 clients just trying to make money, we want 10 clients that truly want to help people and make a difference!”
