Dr. Samantha Warren is a state licensed audiologist that earned her Bachelor’s of Science in 2010 and her Doctorate of Audiology from Illinois State University in 2013. She is a fellow of the American Academy of Audiology, holds the Certificate of Clinical Competence from the American Speech, Language, and Hearing Association, and is an active member and former executive board member of the Colorado Academy of Audiology.

"My interest in audiology began after the advice of physician family members that a career in medicine would not offer me the patient connection I was after.  Instead, I started to pursue speech therapy in in order to get the relationship I was after with patients, but learned quickly during the required audiology courses that audiology was my true passion. I love that audiology combines diagnostic critical thinking, an ever changing technological aspect, as well as the ability to grow with patients and their families. I love getting to know my patients intimately, and since moving to Colorado in 2013 I have been able to see my patient's kids and grandkids grow up, celebrate their milestones, and share the excitement of the start of my family in 2018! I enjoy working with pediatrics and adults alongside the medical team members and feel passionate about auditory rehabilitation when working with hearing aids.

When I’m not in Boulder or Lafayette seeing patients, you can find me at home with my husband, daughter, and dog working in our yard or hiking our favorite trails in Rocky Mountain National Park. We enjoy climbing mountains but prefer the less crowded 13ers to 14ers, and love golfing all over Colorado."
