Leadership Development Opportunities

The EPHLI experience allowed me to increase my abilities by providing self assessment tools and a support structure that guided my leadership development in several ways. The systems thinking training helped me better understand where I can affect a variety of issues by revealing effective leverage points. The individual development plan and coaching focused my career direction and improved my management skills. Additionally, and most importantly, the EPHLI program allowed me to network with other leaders for the purpose of addressing an important problem immediately affecting Georgia that would otherwise not be addressed.


The CDC and other EPHLI cadre were extraordinarily supportive and facilitated my learning by providing a conducive atmosphere. They provided direction and guided inquiry as is essential for leadership training. Unlike other programs I’ve experienced, EPHLI was not adversely affected by administrative or logistic issues. This allowed my cohorts and me the opportunity to completely focus on both our project development and expansion of our leadership capabilities.


I am humbled by having been allowed to experience this opportunity. I would like to encourage any mid-career environmental health professional to pursue being part of future EPHLI cohorts.
