Jill True

B.S., H.I.S.

Hearing Instrument Specialist

Jill graduated from Colorado State University with a Bachelor’s of Science in Human Services. She has been working in the Northern Colorado area for seven years as a Hearing Instrument Specialist, and in the medical field for the last 20 years.

Jill enjoys the field of audiology because it allows her to build relationships with her patients and their families.  She loves how improving the hearing of her patients helps connect them with their loved ones and the world around them.  In 2015, she had the privilege of going on a mission trip with the Starkey Hearing Foundation to Congo and Democratic Republic of Congo to fit hearing devices to those without access to better hearing.  She works primarily from the Boulder office, also helping with the administrative aspects of the department, and is credentialed to work with several third-party hearing aid distributers. 

Jill loves to spend time with her three adult children and her husband, Brad.  She also enjoys running marathons, hiking the beautiful Colorado mountains, and is currently training to climb Kilimanjaro!
