I met Bill when I got licensed at 16 as he was my parent’s agent. Now, 17 years later I am lucky to still be insured with him and be a part of his team. Starting as a customer and now a team member, I can tell you how much our team cares. We will fight for you and love to help you in any way we can. I am licensed in Property and Casualty and work as a Service Representative in Bill’s office. I am excited to meet all of our customers and build a relationship with each of you. I have 15 years of experience in insurance, and this is my favorite of all the insurance jobs I have had. A few fun facts about me are that I am a total nerd. I love to read, jam out to music, study psychology, and go to movies at least weekly. I am also obsessed with Halloween, and you can frequently find me at haunted houses. Give our office a call and let me know how I can make your insurance experience easier.

I love working for Bill Mahaffy’s State Farm Agency. I’ve been with his agency since August 2022, but I have worked with State Farm since September 2021. Until I started working for Bill, I didn’t know that some State Farm Agents could be so caring and considerate of customers. This is one of the few agencies that really take care of their customers. I’m licensed in Personal Property, Casualty and Life insurance.

My husband and I moved to Colorado, from Texas, in October 2020. Before I got into insurance, I was in banking for 30 years. We have two sons, and both are married. I’m excited to say, we are having our first grandchild February 2023. I love the mountains and hike as often as possible. We love to grill in our backyard and have family over often. I have no plans to change careers since I have found this amazing company and bosses to work for.
