"Just wanted you to know that I have had nothing but good experiences with [our underwriting contacts at GUS].  Between the two of them, I am more inclined to submit accounts to Griffin than anyone else.  The response time to my requests for quotes and endorsements is much superior to anyone else that I work with.  ....I look for coverages and response time, and so far, Griffin has the top spot with our agency from all the GA's that we deal with.  Thank you and your extremely competent staff for making our job easier and looking good to our clients!!!"

"Just a quick note to let you know how much I love working with [our Underwriting Assistant at GUS]!  She gets every request I send taken care of promptly and correctly.  I have never once had a poor experience working with her, and I believe she's the only rep at any GA that I can say that about.  Every time I get a cert or an endorsement back so fast I am pleased again and say "I love [her]!  She is so on-the-ball!"...She's awesome!"
A.K., Kirkland, WA

"Griffin Underwriting's remarkable service is nothing short of phenomenal.  Your speed, accuracy, courtesy, and attention to detail are clearly place you in a different league from your competition.  You may not always have the best market for a particular risk - for one reason or another, but in all of the other important areas you folks really shine.  There have been times when I will divert business to you when I know there are other, perhaps less expensive markets available - just because of your outstanding service.  I just want you to know that I appreciate the efforts that you put forth.  Thanks again to all of you!"
K.H., Port Angeles, WA

"Thank you again;  you guys are so easy to work with!"

"Thank you so much.  It is becoming a rare and lovely experience to have such prompt and accurate response as we get with Griffin!  With many other brokers and companies we are constantly being frustrated with slooooow, inaccurate work, accompanied by a careless attitude, which makes it really hard to get and keep clients!  THANK YOU!"
M.L., Blaine, WA
