Since 1994, Colorado Access has expanded significantly and has become a premier nonprofit health care plan for Coloradans. There are no secrets to the success of our company. We simply take pride in our work and make it a top priority to do right for our members and community. We believe the single most fundamental part of our work is serving our members.

Caring, helpful, diverse and kind are just a few words that describe the staff here. I am very proud to be leading such talented and compassionate employees; they are our true asset. Our members’ challenges and questions are treated with value and urgency, and our staff works to meet or surpass their expectations.

We are highly dedicated to being the leader in excellent access to great healthcare. Our goal for our members is to maintain a healthy lifestyle. We do this by developing resources and programs that help. This information can be found on our Member Resources page.

Our website is a great road map for information on good health. Please take your time to view our website in detail and let us know of any questions or concerns you may have.

We're Colorado Access. Caring for You & Your Health.

Dr. Marshall Thomas has been with Colorado Access for 17 years.
