What is in it for me  “WIFM”..  my goal in the next two years is to hopefully provide members with a tangible benefit.”

Alexis Pangilinan – Secretary

A recent graduate of the Occupational Environmental Safety Management program at University of Hawaii, Honolulu Community College. She is a professional member of ASSE’s Hawaii chapter, WISE Hawaii Chapter and Chairman for the WISE Hawaii Mentoring Program.

“’What does safety mean to you’ I took this to heart. I realized that it’s not only ensuring the safety of each worker but also creating the culture. Thus it becomes a way of life on and off the job. It’s being the liaison between the field and management to ensure the relationship is a healthy one.”

Daniel Kaui – Treasurer

Daniel was born and raised on Kauai.  He left home after high school and served 23 years in the United States Marine Corps in Aircraft Maintenance and six of those years were in Safety and Quality Assurance.  After his Military service, he earned a B.S. in Professional Aeronautics with a minor in Safety and a Graduate Safety Certificate from Embry-Riddle Aeronautical University.    He also obtained his FAA Airframes and Powerplant Certification.  Daniel worked four years as Aircraft Safety Inspector, seven years in Construction Safety and currently provides safety coverage for High Risk Training at Joint Base Pearl Harbor-Hickam .

“I have been a member of ASSE since March 2008. I would like to help our chapter grow to become one of the role models of ASSE nationwide.”

Adam Cotton – Delegate

Adam grew up in a small town in Montana called Cascade.  Located at the mouth of the Missouri River and in the Rocky Mountains, outdoor activities and sports were a common way of life.  He lettered in football, basketball, and track all four years of high school and after graduating, with 42 kids in his senior class, he went to college at Montana Tech on a full ride scholarship to play football.  He graduated with a Bachelor’s Degree in Occupational Safety & Health.  After college, he did not dive right into the safety professional role, but instead managed a YMCA fitness center and was also an assistant coach for Montana Tech’s football program.  His safety career started a few years later in Phoenix Arizona with a civil contractor doing work that ranged from underground utilities to waste water treatment plants.  While bass fishing with a college friend, he was introduced to Hensel Phelps Construction Company and before long he was working for HP in Northern California on various project from San Jose to Fresno.  Work was picking up in Hawaii and Guam, so after 4 years with the company he was asked to relocate to the island of Kauai.  It didn’t take long before he was chasing pigs in the hills and fish in the ocean and settling in to the island lifestyle.  Currently Adam is the Director of Safety & Health for Hensel Phelps and oversees all their work from Hawaii to Guam.  When they have free time, his fiancé and he will most likely be chasing waves with their boards or chasing dinner with their bows and arrows.

“I have been involved with ASSE for some time now and always look forward to the wealth of knowledge provided by the facilitators and attendees.  I don’t think I would be where I am today without the guidance and mentorship of the people involved with the local chapter.  Through the Hawaii Chapter, I hope that I can also contribute to making Hawaii a safer place to work, live and play.”

“Aloha, I have been a member of Hawaii ASSE for ten years, but only in the last few years can I truly say I was an active member.  The main reason I’ve gotten more involved is because I’ve slowly started learning about what ASSE has to offer and it’s motivated me to be part of the future of our chapter.  I’m excited about the potential we have for engagement and leadership.  The most important thing we need to focus on is communication; making sure our members are in the know about chapter happenings and even more important, solicit input from our members on what they think will make our chapter better.  I hope to be an effective conduit for two-way communication between membership and the Executive Committee; I look forward to your feedback!”
