While many Realtors claim a commitment to integrity, validating such statements can be challenging. As a husband and wife team, we substantiate our unwavering dedication to integrity through distinguished careers which have entrusted us to safeguard lives, property, and the financial assets of others.
Brett retired after 30 years of service on the Fire Department and continues his Grandfather's legacy in real estate sales with the guiding principal that your word is your bond. Cathy held diverse management roles for over 15 years with two private equity industry leaders in both commercial and residential real estate.
When we began real estate sales together in 2017, we felt it was imperative we align ourselves with a brokerage that supported our principals for honesty, high standards and ethical practices. Proudly, we represent Berkshire Hathaway, a brokerage respected worldwide for its integrity, first-rate service, and solid financial strength! Our choice has been validated time and again, as Berkshire Hathaway is consistently recognized as one of Fortune's World's Top Ten Most Admired Companies. These things matter to us, and should to you, too, when choosing who will represent you in a real estate transaction!
We know there are many motivations that create the need for people to buy and sell homes. Our backgrounds and relaxed, no pressure demeanor have proven to serve our clients well with the utmost of care and responsiveness. We think Warren Buffett, our Chairman and CEO, states it best, "A home is one of the most important assets that most people will ever buy. Homes are also where memories are made and you want to work with someone you can trust." We look forward to providing our knowledge and guidance in helping you make your best real estate decisions. Together, let's "Find Your Perfect"!
Specialty Designation:
Certified SRES (Seniors Real Estate Specialist): Providing specialized support and guidance to buyers and sellers age 55+, as well as assistance to family members helping senior loved ones' transition to new living arrangements. Senior agents create a customized plan and can recommend a vast network of services to help make your move as smooth and easy as possible, whether downsizing, finding a single level home, choosing the right 55+ community or transitioning to assisted living. When making one of life's most important decisions in your golden years, call on names you can trust, Berkshire Hathway and Cathy Zielonko.
