I started a small consultation/training business about nine years ago. Debra at Trident has been invaluable in helping my business steadily grow from what started out as me with a few small clients, to what is now a cadre of trainers with major clients across the US and Canada. I like to think I am a success story, but the truth is I had a good idea and then surrounded myself with incredibly professional folks. Fortunately for me, Debra is one of those folks. She absolutely cares about my vision and is incredibly responsive to all of my insurance related needs. If you’re looking for insurance, or perhaps considering changing agencies, I can wholeheartedly recommend Debra Jackson at the Trident Agency!

Always have great service from The Trident Agency for all of my insurance needs…from home to auto to earthquake to umbrella policies!!  My one stop shop!!  Best prices along with excellent service by answering all of my questions!!!  I really sleep comfortable knowing that my family and home and my possessions are safe and secure through Debra and Travis.  I even had Travis give me auto insurance for one day while sitting at AAA to purchase tags for my daughter’s car that had the insurance lapse on.  Trying to sell the vehicle, with expired tags is against the law.  After becoming aware of that, Travis had done all necessary steps to get the tags in my hand and the vehicle sold, all within 2.5 hours!  Exceptional service!!!!

foy insurance has been our broker for almost 10 years. They have saved us money on our E&O, GL, H&W and commercial policies almost every year. Customer services, quality products and reasonable pricing; they say you can’t get all three at once; but Foy makes you feel like you did.



If you really want to protect your business, want someone who understands your industry, and if you want a broker that is there for you and will stand by your side during your claims process, you need to call jesse and his team.

Prompt and professional. I quickly found out that their team knew my industry like no other. They quoted me for coverage that fit my needs and saved me thousands of dollars a year. Initially, I didn’t want to switch my insurance because it felt like a hassle but I started to consider my previous insurance situation, my agent never even called me when I had a claim.



Their team knew our industry extremely well. Once they reviewed my coverage, they found many gaps in my current insurance. Now I have an insurance program that I know covers our business. Sleeping a lot better at night…



Foy & Associates set me up with great insurance & great pricing. At the same time providing excellent customer service and professionalism
