I have been in banking and real estate for over 25 years. Starting as a bank teller in 1991, I worked in commercial, private, and personal banking. I found my passion was residential lending and educating consumers in making one of the most important decisions in buying a home. Determined to provide more service, I obtained my Real Estate license in 2003. In January 2011, I established Harmony Brokers. I wanted to provide a “One Stop Shop” for consumers to provide Real Estate services as well as lending.

I grew up in the real estate industry. Both my parents were realtors, and I spent many Sundays at open houses with them. I have lived in Colorado my entire life and know all the great spots for vacations. I moved my three children from Denver to Loveland in 2000, and we call it home. For 28 years, I was a marketing consultant for small to medium business owners.
My passion is every child should have “roots.” A place to call home and create new memories. I love to take family vacations with my three children, their spouses, and my six grandchildren. Doing yoga and spending time outdoors is what I do with my free time.

I love being active, going to and participating in sports, concerts, and family events. I am a director at a Pre-school and School-age program and coach gymnastics as well at our family businesses. I enjoy this very much but wanted to expand and move into real estate after growing up with a builder. Being very family-oriented, I love being able to help people find a place they can call home! Home is where the heart is!

I bring over a decade of experience in sales and consumer marketing. My own stressful experience with the home-buying process inspired me to become a realtor, so I could help others navigate this significant journey with ease. I love helping people realize that homeownership is not only achievable but can also be an enjoyable experience.
Originally from Denver, I moved to Fort Collins to create a supportive environment for my children. My family includes my wife, three kids, two dogs, an axolotl, a fish, and a snake. I’m passionate about making real estate dreams come true. In my free time, I enjoy music, pickleball, woodworking, aquatics, and engineering.
If you’re looking for a dedicated and compassionate realtor in Fort Collins, I’m here to guide you every step of the way. Contact me today – I’m here for you and ready to help you achieve your homeownership goals.

I’m a dedicated real estate agent who believes that buying or selling should feel exciting. My commitment is to bring a fresh perspective, strong work ethic, and deep commitment to my clients from our first point of contact, all the way through closing.
I’ve lived in Colorado my entire life and grew up in the Denver-metro area. I spend most of my time outside of real estate as a musician playing drums, piano, DJing, and songwriting. I also spend my time at sporting events, concerts, fishing, snowboarding, and lifting.
Choosing the right real estate agent matters. As a newer agent, I offer something unique: unmatched dedication, responsiveness, and the drive to go above and beyond! I’m excited to help you find the right buyer for your current property or your next “home sweet home!
