I used Ethan as my agent for both buying and selling my house when I moved cross-country for work. I cannot say enough good things about him and the team he works with. I purchased my house in the middle of the pandemic when bids were crazy and it felt impossible to find a home. He knew it wasn’t going to be my forever house, so we had to be strategic. This guy has HUSTLE. I was the third buyer in line for the amazing house I ended up with and got a great price. When I went to sell, I was aiming for the top of the market and knew I had a special house that could get it. We came up with a plan and he and his team executed it flawlessly. We ended up s...

Outstanding team of professionals. Top-notch marketing, sales and service, as well as attention to detail. Absolutely first rate!

The Zach Zeldner Team were a pleasure to work with. They truly operate as a team. From beginning to end the communication and attention to every detail was above and beyond my expectations. I wouldn’t use anyone else. William was always very responsive and patient with us as were the rest of the team.

We couldn't be more grateful for our experience working with Zach and his team to sell our home. From start to finish, we felt completely supported and confident in their expertise. The marketing was outstanding – the professional photos and materials beautifully showcased our home. They were present at every showing, providing valuable feedback afterward that kept us informed throughout the process. When it came to navigating offers and closing, their attention to detail was impeccable. Every "t" was crossed and every "i" dotted, ensuring a smooth transaction from contract to keys. Their proactive communication meant we never had to wonder about ne...

We had the pleasure of working with Lauren O’Neil at Zach Zeldner, and she is outstanding. Lauren went above and beyond, helping us not just with the transaction but with a holistic assessment of Boulder living. She dug into local laws, community insights, and even set up resources to make our move seamless. Lauren brings a rare mix of grit, deep market knowledge, and genuine care. She made sure we were informed, confident, and connected every step of the way. If you’re looking for someone who will hustle for you, guide you with integrity, and truly understand the Boulder community, Lauren is the agent you want by your side.

"What an exceptional team! My family sold our house with Ethan and the team at Zach Zeldner representing us. They are professional, easy to work with and helpful in more ways than expected. They are in the know with housing trends, styles (staging), and are very educated about the current market. We would recommend this team if you are looking to sell your house or buy a house in the greater Boulder/Louisville area."

"Had a very easy, swift home buying process with Will and his team! They were a great resource through the process and turned out to be much more reliable than our Escrow company in terms of getting information to us in a timely fashion. Also I am fairly certain I would have paid a significantly higher price were it not for Will’s negotiations with the selling agent. Highly recommend!"

"Hillary was absolutely amazing. She was able to provide a completely stress free and enjoyable experience to an otherwise stressful process. Her and the entire Zeldner team are the best there is. 10/10 would recommend!"

"We had an outstanding experience working with Ethan Bullock. From the very beginning, Ethan was proactive, detail-oriented, and genuinely had our best interests at heart. He consistently flagged potential issues we hadn’t considered, responded quickly to every question, and made sure we had all the information we needed to make a confident decision. It was clear throughout the process that he truly cared about helping us make the right choice—not just closing a deal. Ethan’s team, The Zach Zeldner Team, was equally impressive: responsive, organized, and incredibly knowledgeable about the Colorado market. If you’re looking to buy or sell, I highly r...

"What a great team! Always accessible and responsive and helpful and patient."

"I have never seen anyone put so much pride and effort into selling a home. We have used Zach and his team twice now and it quite literally has been the best experience. Look no further than Zach. Him and his team go above and beyond every step of the way. From getting it show ready, to marketing in unique ways across many channels, to helping with the inspection process once under contract, to great communication all the way to signing the contract- all while we were already moved abroad! Thank you, Zach and Team!"

"We worked with Will G and the entire Zach Zeldner group to find and purchase a property in Boulder. As out-of-state residents, we needed to rely on the team for their local insights, which were spot on. Will was conscientious and took great effort to make sure we had all of the information necessary about the properties we were interested in, so that we could make informed decisions before we even saw them in person. Will visited the property, sent us detailed videos, and talked through everything he saw with us. He then expertly negotiated for the property we decided on, and we wrapped the whole purchase up in record time. We couldn't be happier a...

"I'd like to compliment Zach and his exceptional team for an under-promise over-deliver transaction. They exceeded our expectations at every turn. I highly recommend them!"

"Smooth execution, thoughtful partnership all along the way. This was our sixth transaction with Zach and his team. We have nothing but good things to say. They helped us locate a buyer off market and assisted us extensively through the close."

"Absolutely top notch, flawless professionals with unsurpassed market knowledge and skill. They really have no peer in Boulder and beyond. This was our second major transaction with Zach’s team and it was truly outstanding. Will Grieg, especially, went above and beyond all expectations to ensure a perfect purchase transaction while we were out of town. He helped us find an off market property and carefully attended to every detail. The result was a dream come true transaction. The same level of dedication and excellence is evident with all members of this team. We are raving fans."

"It was very enjoyable to work with Will on purchasing a property. He listened well to my wants and needs and was able to find a place that fit my lifestyle and desires. He has great local market knowledge and provided a low stress, no-pressure environment. I would recommend him to anyone in the greater Boulder area."

"Zach and his team are exceptional at what they do! It begins with Zach who leads by example in professionalism, courtesy, attention to detail & knowledgeable service consistently delivered throughout- thank you for all your help, a pleasure to work with."

"Zach was incredible to work with. He was professional and went above and beyond. He not only helped us find a house we love but we appreciated his insights when it came to offers and negotiations."

"Zach is the top real estate broker I've come across in my lifetime. Knowledgeable, personable, balanced, patient, trustworthy, and always looking out for the client. An absolute pleasure to work with and I would recommend him to the most demanding client and situation as he's up to that standard."

"Zach Zeldner and his entire team are simply the best! Attentive, caring, knowledgeable, and professional. He and his team understood our needs and worked diligently to help us achieve our goal of selling our parents' longtime home. He is knowledgeable about the regional market and guided us with expertise. He and team member Will Greig took time to take us on in-person visits to see comps in order to help us in our decision-making process. They rescheduled their photographer/videographer (due to weather-related issues) multiple times to help us get the best view photos and videos possible. All of the team members were kind, knowledgeable, and respe...

"It is always so difficult to laud someone in such little ink as an online review will allow, but we do so with great pleasure in recommending Will Greig, and not just as a profoundly gifted real estate agent, but as a gem of a human being. Will brings a very high degree of sensitivity, kindness and emotional intelligence to his work – and not because he needs to, but because that is just who he is. He simply has a way with people, which is not a learned skill, but one that is inherent in him. He is an excellent listener, and he always works to find the right solution for each person. He did so with us, and we are very happy to have landed upon his ...

"Zach and his team are THE BEST, in all respects. To take just one small example, as the drone videographer was finishing up, Zach said, "Be sure to get footage of the Viewpoint trail." I had not mentioned anything to Zach about that trail, or its importance as an amenity at this location, which is huge. But Zach knew about it., and made sure it would be shown in the listing. In that and other ways, Zach and team appreciated the qualities of a unique property, and presented it at its best. As sellers whose last experience in the real estate market was 40 years ago, we greatly appreciated how responsive and supportive Zach and his team were at every ...

"I recently had the pleasure of working with Will and I can’t praise him enough. Will goes above and beyond in every aspect of the home buying process, making it an experience unlike any I’ve ever had. Throughout our interactions, it was evident that he cared deeply about my needs and preferences. He took the time to understand what I was looking for and provided tailored recommendations that aligned perfectly with my vision. He was always available to answer questions, provide insights, and offer support, often going out of his way to make things as smooth as possible for me. The entire process felt less like a transaction and more like a journey w...

"I didn't know real estate brokers like Zach existed! He was fantastic at every stage of selling our house. His team - and it is a team in the best sense of the word - worked together seamlessly to show our house and garden to best advantage. They actually loved our property and that showed through. The remarkable video they produced was key in getting a very quick sale to very happy buyers. His response time to any query, large or small, is lightening quick. He radiates integrity and his energy is phenomenal. He turned a dreaded chore into a memorable and enjoyable expereince! I never thought I would say that!"

"Working with William Greig was an absolute delight. His extensive knowledge of the local market and dedication to finding the perfect home for us was evident from day one. Will was always available to answer our questions, provide valuable insights, and guide us through every step of the process with patience and expertise. His professionalism, warmth, and genuine care for our needs made the entire experience not just stress-free, but truly enjoyable. We couldn’t be happier with our new home and we have our wonderful realtor to thank for that. Anyone looking to buy or sell property would be lucky to have William Greig as their agent."

"Zach is the absolute best! We have bought and sold several properties in Boulder County, and he is our go-to professional to help make this stressful process go smoothly. He is professional, works with integrity, and gets the job done. He has connections in the community who also respect and value working with him, which is so helpful when getting a home ready to sell. When unexpected bumps occur, which is to be expected, he helps smooth them out with his calm demeanor and keen approach to all things real estate! I would work with no one else!"

"Will helped us with the purchase of our first home, and he was a great guide throughout the process. We asked a lot of questions, and he was more than patient in ensuring we were confident at each step. Will was very reliable and accommodating of our objectives. He taught us a lot throughout, and we successfully landed a great house below asking. We would highly recommend Will."

"Selling my house with zach and his team was seamless and very swift... we had multiple offers after the second day of showings and it was closed a week later. zach was extremely knowledgable, professional and available during the preparation period, the showing weekend and the closing. he made sure that my constraints were met (i needed to rent back the house so my children could finish the school year) and that there was minimal disturbance to my family while the house was showing. his team was also extremely responsive and helpful. the whole experience was smooth. i would highly recommend zach zeldner as a stellar realtor."

"We cannot emphasize enough how outstanding Zach and his team are in Boulder real estate. Zach's sophistication and in-depth knowledge of the market are truly unparalleled, making every interaction a lesson in professionalism and expertise. His attentiveness to our needs was remarkable, ensuring that every step of the process was seamless and stress-free. Most importantly, Zach's unwavering honesty and integrity instilled complete trust in his guidance, allowing us to navigate the complexities of buying and selling (we did both with him!) with absolute confidence. Without hesitation, I wholeheartedly recommend Zach and his team to anyone seeking unp...
