The second Ann Lachat award winner is:

Heidi Hamlin, RN, BSN, COHN


Heidi Hamlin has worked in occupational health since 2016.  She spent five years at St. Luke's Health System in Boise, Idaho working in roles including Registered Nurse, Clinical Educator, and Program Manager in the Employee Health and Occupational Health departments.  She partnered with the Center for Nursing Excellence at St. Luke's to co-present an educational session "Occupational Health Nursing and the Innovative Response to the COVID-19 Pandemic" at the Learning in Education, Administration, & Practice (LEAP) 2020 conference for Idaho Nurse Leaders.  Heidi currently works as an Implementation Consultant for Cority.  In this role she works with clinical leaders in Occupational Health departments to implement a specialized software solution that was developed specifically for occupational health in healthcare organizations. With the pandemic, this has been instrumental in the management of Covid-19 testing, vaccination, and return to work.


Heidi graduated magna cum laude from Seattle Pacific University with a Bachelor of Science in Nursing.  She competed in Track & Field and Cross Country during her four years as an undergraduate nursing student.  Heidi and her husband have been married 30 years and have three children ages 25, 22, and 18. Heidi loves to ride her mountain bike and hike in the foothills near her home in Boise.  She and her family climbed to the summit of Mount Borah last summer, the tallest peak in Idaho with an elevation of 12,662 ft. 

Congratulations Heidi!
