Leadership Development Opportunities

What a valuable training opportunity! The EPHLI has provided me with the tools and resources needed to address issues we face daily as environmental health practitioners. The Institute promotes critical thinking, collaboration and finding solutions to problems. The open dialogue during sessions with the instructors, faculty, mentors and fellows I found to be enlightening in preparing us for public health challenges in the future. This experience has been rewarding and I have grown both personally and professionally from attending. I thank EPHLI for the opportunity and for assisting me in enhancing my skills as an environmental health leader.
