What Our Clients Think About Us

I heard about Doner-Horsley through a friend, and I am elated that I did. I was looking for insurance coverage for my modified car that was deemed uninsurable by any other insurance brokers. Not only did Doner-Horsley find me great, affordable coverage on my car, they saved me money on my home insurance as well. Colin and Jo-Anne are incredibly knowledgeable. Response times were quick and reliable. Their veracity and dedication to customer service is beyond any other company I have encountered in the past. I highly recommend Doner-Horsley Ltd. and could not be happier with the service I have received.

Noah Kalinsky

Rick Costello & Blaire Hadwen at Doner-Horsley have looked after our insurance needs for both our business and our home for several years now. We are very pleased with the service and have found that all questions and concerns are dealt with promptly and efficiently.

Kawartha Utilities

Just a quick note to say thank you so much for all your help over the past year (or so!) You have been so wonderful to work with and have helped us with insurance for some really big milestones in our lives including our first home and now our wedding.

Sam Lemieux

We recently moved our Contractors Pollution Liability policy to Doner-Horsley Insurance and want to acknowledge the fantastic service we have received from one of your brokers, specifically Brenda Giroux.

Service Master

Each time we have a reason to call Rick Costello or Blaire Hadwen regarding our insurance, it becomes clearer and clearer how committed they are to customer service. Doner Horsley’s actions and our conversations truly make us feel that they treat their clients just as they would treat their own family. They have the perfect blend of professionalism and neighbourly caring.

Dave Dobinson Excavating Inc.

In the fall of 2013 my insurance policy was up for renewal and felt that my broker did not understand my requirements for insuring my truck and horse trailer, so in frustration I posted a question on a local horse bulletin board. Among the replies was one from Brenda Giroux offering her services as a broker.

Fran Zahorchak

As always – excellent service. It is you Lois, and your service over the years that I have loved and valued.

Anna Wickens

Recently we purchased business insurance and fleet insurance through Brenda Giroux of Doner-Horsley Insurance Brokers Ltd. Not only did we receive professional, courteous service, we also saved money on our policies. Brenda was a real plesaure to work with and in our opinion, she went the extra mile to save us money and find the insurance company that would best suit our needs.

MacMillan Vending

We have been with the same insurance company for many, many years. When it was time to renew our insurance this year we decided to see what the competitors were offering. I was pleasantly surprised with what Doner-Horsley Insurance had to offer. Not only was I provided almost twice the amount of coverage, but we also saved over $400.00 per year!

Rhonda Bear & Paul Lendt

Have referred two people with unique situations to this wonderful brokerage and not only were they able to assist, they did it quickly and professionally. Will refer more in the future knowing they will be taken care of. Thank you!
