After college, she moved to Garmisch, Germany where she worked for the next year as a ski instructor in the Bavarian Alps. In 2002, she returned to the United States to attend optometry school at the new England College of Optometry. She graduated with her doctorate in 2006 and in 2007, she completed her residency in Primary Care and Pediatrics at NOVA Southeastern University in Fort Lauderdale, FL.

In November 2010 Dr. Hill received her fellowship from the College of Optometrists in Vision Development and Vision Therapy. In addition, she has been a fellow of the American Academy of Optometry since 2009.

Dr. Hill opened 20Twenty Eyecare with Dr. Sarah Kirkpatrick in 2013 and then on January 1, 2020 she was ecstatic about opening Vital Vision Therapy. Providing vision rehabilitation for children and adults has been a career dream for Dr. Hill. Now, with the opening of Vital Vision Therapy, she couldn’t be more excited to finally have a vision therapy clinic to serve the needs of Montanans locally and statewide.
