Phil and his staff are the Best of the Best. I have used the services of Cornerstone Insurance for many years. I have recommended Phil and his staff to all my family and friends and all have been exceptionally pleased. I would highly recommend Phil and Cornerstone Insurance to anyone.

I have been buying insurance from Phil forever. He always finds me a great deal with all of the coverages that I need.

I am in the property management business and have been involved with Phil and his staff at Cornerstone Insurance for well over a decade. When I first met Phil I was impressed with his knowledge of his industry and his concerned and friendly approach with his clients. I soon began referring my clients to him for their insurance needs and many have been Cornerstone clients for several years. When ever I've needed to deal with a claim, the Cornerstone staff has been on top of the issue and I couldn't be happier with their coverage and customer service.

I work in the HOA world and have been very pleased with the service I have received from Deedy & the staff at Cornerstone insurance. They are always prompt, informative, and very understanding. I love working with Deedy & hope to continue to do so!
