Leadership Development Opportunities

I am thankful to the CDC/NCEH/ATSDR for its commitment to providing advanced leadership, resources and funding for environmental health professional development. 


It has been time well spent for me.  National Environmental Public Health Leadership Institute (EPHLI) was well organized, from logistics to curriculum.  The curriculum was comprehensive in that it introduced several different leadership and psychological models and provided guided application of them to a single project.  The competency-based approach of applying the various models and receiving continuing feedback as it related to my project provided me with a wide range of tools for future development projects.  In addition, by participating in this institute, I have refined my knowledge of my own personal leadership strengths and challenges. 


EPHLI has been very intensive in terms of time commitment and structured assignments.  Although I was aware of the basic components of this leadership training opportunity, I didn't realize how comprehensively the project would integrate the training materials.  At times I struggled with my project, trying to see how the different models applied to a project that depended so much on the contributions of external participants. 


The people also made the program a success.  Mentors were dedicated to providing support to fellows as needed.  The role of mentor was valuable particularly in fostering my project development and enhancing the learning experience.  Cohort and smaller team interactions created an atmosphere conducive to developing long-lasting networks and will continued to be highly valued.
