Biography coming soon!



I am a proud fourth-generation pest control professional. I started working for my dad at Chuck Sullivan Exterminators, Inc. (DBA:Peststop) in 2005 before deciding to veture off on my own and work for a couple other great pest control companies. In 2015, I returned to take over the family business. The experiences gained and lessons I learned from working for others has given me a unique perspective of not just how I run my company but how others run theirs. Our industry is as diverse as it is great. I am dedicated to ensuring it stays this way. Working my way through our industry and experiencing the many challenges that all our companies face helps me to relate and better represent the needs of our industry.

I am always learning and working to become the best leader I can be. In 2014, I became an Associate Certified Entomologist and was later selected to be part of NPMA’s first ever Executive Leadership Program (ELP). I served on NPMA’s diversity committee and I currently serve on the PestVets and Technical Committee. I also serve as the Chairman of Kitsap Counties Noxious Weed Control Board and WSU’s PMP Advisory Committee.

There’s nothing like the pest control industry. It’s an honored to give back by serving you and your business’s needs as Vice President of the Washington State Pest Management Association. I thank you all for your confidence and continued support of our industry.


Thank you,
