"We decided to work with Zach to purchase a home in Boulder after meeting with several other realtors in the area. Zach is extremely knowledgable about the Boulder market, and imparted a good deal of information that helped us narrow down the neighborhoods we should consider. We worked with him over several months, ultimately winning a bid on a competitive property in a desirable neighborhood. We were impressed with Zach's professional manner, his knowledge about the market and value of individual homes, and his confidence in making offers in a very competitive market. We look forward to working with Zach in the future!" - Andrew H.

"Working with Zach was effortless. I hired him based the reputation he's built in Boulder over many years and it's obvious why people speak so highly of him. He is everything you want in an agent (dedicated, knowledgable, calm + controlled, discreet) and nothing you don't (dishonest, dramatic, unethical). He's really a cut above the rest, and I'll happily work with him again as well as refer him out to my network." - Liz337
