ABOUT WILL
With an ideal combination of empathy, skill, and experience William has quickly become one of Boulder's well known real estate agents in the luxury sector. As it always does, the past informs the way William approaches work today. A former Division 1 Track and Field runner turned professional triathlete and small business owner, William is no stranger to hard work and dedication. Always striving to learn and grow, William also earned two Masters degrees from the University of Michigan, the second in Social Work with a focus on Interpersonal Practice and Mental Health.
What separates William from other agents is the combination of his people-centered approach and entrepreneurial nature. With an intense focus on achieving the best possible results for clients William maintains a people centered approach that recognizes the emotional component of any real estate transaction. This helps him to find individualized solutions that put the needs of clients first, always finding flexibility to accommodate the people at the center of this work.
William was originally drawn to real estate by his experience buying and remodeling his personal homes. A genuine people person, he leverages his knowledge and calming demeanor to deliver seamless, low-stress experiences for his clients. He has established a notable reputation for connecting deeply with buyers and sellers and helping them fine-tune their exact objectives. He addresses every situation with a level-headed approach. William truly thrives on helping everyone find their place to feel at home.
A New York native, William now resides in gorgeous Lake of the Pines with his wife Becca, their two daughters and their sweet pup, Bella. There, they enjoy taking walks around the lake, hiking, biking, paddle boarding, and swimming.
ABOUT ETHAN
Ethan Bullock is an award-winning real estate professional nearing 20 years of experience in residential sales, marketing, construction, and development. Regardless of the scale or the complexity of the transaction, his solutions-driven mindset has established a strong record of success. With a focus on Boulder County and the surrounding area, Ethan's deep market knowledge and broad network of relationships create a unique and strategic advantage for his clients. Outside of real estate, these days Ethan can likely be found on the sidelines at his daughters' soccer games or holding court at his favorite coffee shops. A committed athlete and early-riser, he's often in the gym or on single track getting his mind right before the sun rises. He has successfully completed numerous ultramarathons, skimo races, and various other endurance events throughout the US. Ethan has also recently found amateur boxing, and while mediocre at it, is enjoying learning the art of the sweet science.
A proud father and husband, Ethan and Jeni call Louisville home and have two daughters who inspire and amaze (and terrify) on a daily basis. Ethan graduated from the University of Pennsylvania with degrees in Art History and Classics, and captained their D1 wrestling team.
