Leadership Development Opportunities

The Environmental Public Health Leadership Institute (EPHLI) has provided me with a new awareness into my leadership skills and style throughout the internship.  Through the Meyers-Briggs Type Indicator I was able to determine my exact personality type and refine my strengths in my personality traits while adjusting perceived weaknesses to be revised or amended when a certain leadership style dictated so.  Additionally, the Skillscope tool helped me reexamine certain traits and talents that I am strong in while helping me reassess those that needed refinement.  As much as I struggled to adopt and enrich myself with Systems Thinking during cohort sessions, I found myself a Systems Thinking approach throughout the past year in professional dilemmas and problems. As I continue to develop and hone my Systems Thinking skills, I know this will be a powerful approach to identifying and solving future problems in both my professional and personal life.


Most importantly, the EPHLI experiences granted me an opportunity to network and establish professional relationships that had and will have a direct impact on my career.  Soon after acceptance into EPHLI, I was promoted into a new position.  Upon promotion, I was tasked with a major environmental public health problem under one of programs.  It was then I reached out to my cohort and previous cohorts (I – III) for assistance with the work problem.  The response was overwhelming, supportive, and immediate!  Persons from my cohort and previous cohorts provided immediate feedback and recommendations of not only how to approach the problem but also methodologies that were successful and experiences learned in handling the problem.  For this, I am most grateful and appreciative of my EPHLI experience.
