I so enjoy working with Don! I've been a lender in the Seattle area for over 20yrs and Don truly stands out as a supurb realtor. He advocates for his clients, works to find a win-win and communicates regularly. He is especially dedicated to help folks join forces to buy in community, whether it be multi-generational co-housing or friends joining forces to purchase together. I highly recommend Don!

Don is patient, quietly encouraging, and deeply knowledgeable. He knows the market, he knows the people, and he definitely knows houses — we really appreciated his guidance in a few cases where we were feeling unsure about what we were seeing in a walkthrough. As first-time homebuyers, we had a lot of questions, and he never rushed us through them, always happy to explain how things worked in clear terms. We live in our dream home thanks to his help!

As a first time home buyer I was very new to the real estate process. Thankfully Don was there to help walk me thru. He was very patient, answered all my questions in a timely manner, and truly paid attention to my needs. He know homes well and has a lot of experience to draw from. Having just closed on a condo that fit all my criteria, I couldn’t be happier with Dons help. Highly recommended considering him if you’re looking for a genuine down-to-earth agent.

Don helped us buy our first house, and the experience could not have been better. We are so grateful he was our agent!

Don's knowledge of the neighborhoods we were interested in was outstanding, and he generously shared what he knew. We knew very little about the home buying process before we began, and Don's expertise was immensely helpful. He offered everything from detailed answers about our paperwork questions, to a lifetime's worth of knowledge about house systems and construction, to thoughtful insights about lenders. Don was reliably and quickly responsive and available for us throughout the home buying process.

Because we had never bought a house before, Don's negotiation skills were key to our getting the perfect home for us within our budget. He was thoughtful, smart, and effective during the negotiation process. We felt extraordinarily fortunate to have his help.

We also just thought Don was a fabulous human being. It was nice to spend time with him during our house hunt. We enthusiastically recommend him as an agent!

Don was a pleasure to work with and brought a wealth of local knowledge and solid advice. We were looking for a property with the potential for doing our own improvements (basement build-out, etc.) and his background and knowledge of building and remodeling were extremely valuable. During the several-month period we spent looking at house after house, he was patient and responsive to our needs. And once we chose a property, he expertly guided us through the process. Since the home we chose was being listed through the seller's relocation company, we had a more complex landscape to negotiate involving the seller, relo company, listing agent, as well as our own lender that we chose to go with. Don was a complete professional and we even got feedback from our out-of-state lender saying how smoothly things went. I wouldn't hesitate to recommend Don to anyone looking to buy or sell in the Seattle area.
