"We loved working with Dave! He was very knowledgeable and responsive, he helped us find what we were looking for quickly and we would definitely work with him again."


"Dave was great to work with! He was quick to respond to showing requests, and always made himself available. Once we were under contract, Dave kept us updated at every step of the way. He was even on top of local legislation changes to short term rental rules that impacted our transaction, and made sure we knew exactly what we needed to do. I would recommend Dave to anyone looking for a Realtor in the area!"


"Dave is patient, persistent and responsive! I enjoyed working with him and will work with him in the future and recommend him to other buyers and sellers."

His patience, knowledge, flexibility, and professionalism were exactly what we needed. I highly recommend Dave!"


"I was referred to Dave by another Broker and I couldn't have been more pleased with the professionalism that Dave showed. He sold my condo quickly and with a record sale per square foot. I will definitely use Dave in the future and you should too!"


"I have worked with Dave twice now--once for a real estate purchase and once for a sale. He is an excellent agent who goes the extra mile to make sure the process runs smoothly. I discussed my condo sale with more agents than just Dave but went with him because I trusted his knowledge of the market, and I am so glad I did--I could not be happier with my sale experience and the price I got for my condo."

"It was so easy to sell our condo with Dave negotiating the process.

He was also a pleasure to work with throughout the process. He was always timely in communicating, gave great advice, cheerfully worked around renters to conduct showings, and made the offer and closing processes easy and efficient for an out-of-state seller. In fact, Dave went so far as to offer to arrange contractors to take care of inspection items before closing on the sale. Most importantly, Dave's energy and persistence produced great results. I highly recommend him."

—Gordon Seymour

"We were extremely happy working with Dave Greenberg when he helped us sell our property in Keystone! It was very easy to communicate with him, he was always quick to respond, and most importantly, he took care of several critical items for us as we did not live in the area. And most importantly, he helped us close our property in the middle of the pandemic crisis and shutdown restrictions. We are so grateful for him and highly recommend him!"


"Dave helped us sell a fractional ownership in a condo partnership in Keystone. Not many of these are done using realtors and questions aplenty arise during the process.
The process took about 5 months and he kept us abreast of possible interested buyers very well."


"Dave helped my husband and I purchase our first rental property in the Summit County. He provided excellent service from the beginning of the process til the end. We really thank him for being so quick and responsive, so we got our perfect rental property/second home.

We highly recommend Dave and we will definitely use him again if we decided to buy another property in the future."

We never felt pressured or pushed from the buying or selling side, and he was transparent with all the happenings through our process of buying and selling. Stand out realtor in Summit County, highly recommend!"


"My husband and I had met Dave casually years ago and were impressed with his local knowledge, friendliness, and professional approach. When we made the decision to sell our town home in Keystone, Dave was one of three realtors we interviewed.
The choice to contract with Dave as our selling agent was absolutely the best decision. Our home sold for more than the other two agents suggested as listing price. His marketing was extensive and professional. From the the first day after signing the contract to sell until even after the closing of the sale, he kept us informed, as well as giving factual and considerate advise. Dave is a professional and very knowledgable of the real estate market. We were pleased from beginning to end of the selling process."

"Dave is a true professional in the Summit County real estate market with his aggressive style and follow-up skills. He has helped in the sale of two properties I have had in Summit County with both selling very close to the asking price and in a short period of time. I would highly recommend him to any potential sellers and would be confident he would provide them with great service."


"It was a great experience working with Dave. He was very knowledgeable about the Keystone market and provided helpful advice for selling our condo. Dave was there when we needed him, staying in close touch throughout the process. He was able to negotiate an offer at list price and a backup offer over list. Dave is professional, very personable and we would certainly recommend him to anyone buying or selling in Keystone and Summit County."


"Dave was knowledgeable, considerate, responsive and diplomatic. It was truly a pleasure to work with him. Every judgment call that he made, such as advising on which upgrades would be most effective in increasing the chance of sale, proved true. Incidentally, it was very easy to select the real estate firm to go to in Keystone. Dave's company has impressive statistics to demonstrate how effective they are in that market and other Vail ski resort markets in Colorado."


"Dave did an excellent job for us. We had a property that was difficult to sell because of its location. Dave persisted in negotiation details with perspective buyers until a contract could become a reality. His continued efforts were required and he kept track of our needs until the property was sold."


"Dave is an expert in the local market. He understands the properties very well, and has a great grasp on the value of them. He worked very hard to make sure we got the best value for the property we were selling. Dave is exceptionally easy to work with; he's very responsive and always provides timely answers to questions. I recommend him to anyone in need of realty services."


"I just purchased a condo in Expedition Station at the end of 2017 and it was because of Dave's recommendations that it was possible. Dave & I had viewed multiple properties in Keystone & a couple in Breck in the late Fall 2017 and he was very knowledgeable on all of them. He's also very customer based and does not try to pressure you into a decision. At that time it was definitely a sellers market and the places I was interested in sold quickly. However, Dave continued to make recommendations and talk with sellers who he knew were interested in selling and he recommended a condo that I really liked and ended up purchasing that never came on the market.

I would highly recommend Dave as Real Estate Professional.

Thanks, A Satisfied Customer."


"Dave is an expert in Keystone Area Real Estate and worked hard to get us an amazing price for our condo. As an out of state seller, Dave made the entire transaction easy. I highly recommend him and his expertise."

—Matt Grondin

"Dave is an top negotiator and expert in realty sales and marketing. He is the best I have ever worked with and made my sale seem effortless. Thanks Dave!"


"I highly recommend Dave Greenberg to be your Summit County real estate agent. I have used him to purchase my last two homes. He is friendly, courteous and responsive.

He understood my particular needs and helped me find the perfect place to live and call home.

Dave knows Summit County and he also knows all of the people involved in the purchase of a home. I always felt well represented. Dave is very much a professional real estate agent that I would recommend as well as use again."


"We worked with Dave to upgrade from our current place to a new one in the same area. He worked with us to get our unit listed, marketed and sold and to work with us to find our excellent new place. Was always available for questions and guidance and we highly recommend him."


"Dave helped us sell our condo in Keystone last month. His relaxed easy style was appreciated. At this same time don't be mislead David and his team were on top of every detail. His advice regarding pricing and marketing our unit helped avoid a lot of unnecessary work and money.
When we needed expert handymen to assist in clearing the buyers few items he recommended people who were timely and affordable.
Made our transaction a breeze."

"We closed on the sale of our house in Alma today and I would like to commend Dave for his professionalism, local knowledge and for going the extra mile in getting issues resolved. It was a pleasure to work with him and I would highly recommend Dave if you are interested in buying or selling a home.


"Dave Greenburg, of Slifer Smith & Frampton Real Estate was the real estate professional we worked with on the sale of our cabin in Colorado. This wasn’t a typical transaction. Because of where the property was located, it was necessary to deal with the National Forest on several issues and the health department on the Septic System. Dave went out of his way to make sure all the paperwork was handled on a timely basis. He was great at following up to make sure everything was done right. The lady at the title company, who knows Dave, told us that we had nothing to worry about (we live out of state) because Dave is so dependable. My husband and I would certainly recommend Dave without any hesitation."


"Dave is a long-time local with an intimate knowledge of the market. He's responsive and works tirelessly to make sure his clients are satisfied. Dave maximized the sale price of our home and still managed to negotiate a lease-back agreement so we would not need to take out any additional loans in purchasing our new home. The entire process was seamless and we would not hesitate to hire Dave again."


"Dave helped us sell a condo in Keystone which had been in the family since 1972. This was an emotional process but Dave had a buyer within a week that offered very close to the asking price. Even though we had to go through an attorney with all kinds of special requests and amendments, he handled it all with knowledge and class and assured us it was no problem! Thanks, Dave, for your expertise. We always felt we were in competent hands and that made us feel very comfortable with the sale."


"My wife and I have worked with Dave on 5 separate transactions over the past 3 years. Every transaction was negotiated on our behalf by Dave with great results. Again and again Dave demonstrated a high level of competence and professionalism. We are very thankful that we found Dave and that we consider him to not only be a great realtor, but also a friend.

Steve & Janelle"

"In 40 years my wife and I have bought and sold 17 properties. Dave was the best realtor that we have worked with. Had two offers in the first week on the market, closed in less than 90 days. He took care of everything from A to Z. Communication and follow up was excellent. He made the process seamless. Highly professional. You won't go wrong with Dave.
Doug & Susan Kelly"


"We have bought and sold many properties, and Dave was one of the best realtors that we have ever worked with. He is very personable, and was extremely generous with his time-even making himself available to show the property to our children who were visiting from out of time on a holiday weekend!
He responded promptly to all of our inquiries, and his knowledge of the area was very helpful in finding services that we required.
We would recommend him to anyone with real estate needs in Summit County."


"Working with Dave was great. He made the whole process of my real estate purchase seamless and easy! I look forward to working with him in the future..."

—justin thiede

"Dave was extremely responsive to my calls and text messages. I communicated what it was that I was looking for and even though there wasn't much inventory, he was able to identify several properties that would meet my needs.

Dave was always on-time with our meetings (actually was there ahead of the expected time) and was very informative as to what was going on and what to expect. He made the process seamless, from identifying the property, to the contract, inspection and closing. He has a pleasant personality and I felt very comfortable talking with him, not only about real estate, but other topics as well.

As this is a small mountain community, I expect to run into him on occasion and would welcome a chat with him anytime."


"We bought a house from out of state, a tough goal and Dave made it so painless! he was ready to tour us till we said we'd had our fill. Concentrated weekend time was just the start, as we were constantly in contact with follow ups by phone. He catered to our spontaneous visits and ultimately proved to be an excellent negotiator. Once the deal was secure, he set us up with several exceptional local contacts, including management agencies and inspection. He has been generous with his time and energy even after the closing. In short, a true professional."


"Dave was very helpful in selling a "difficult" piece of property we had tried to sell working with another realtor in prior years. He was helpful, knowledgeable and available whenever we needed him. He made the process quick and painless. I highly recommend him and would use his services again if I find myself in need of an agent."


"This is the second time we have worked with Dave in the past 4 years. He is very knowledgeable of the market, listens to our needs and always available for assistance."


"Dave did a great job with the sale of both of our Condo in Keystone. He selected the right price point for the condo to get the maximum sales price and to sell the condos in one month. I would recommend him and use him for all my summit county real estate needs."


"We were impressed with the sales record of Dave and his company, Slifer Smith & Frampton Real Estate. Their average days on market and history of getting close to asking price were impressive. While three other realtors told me that our home was worth no more than $XXX, Dave said that he could get about $20,000 more than that for our home. And he was right! In fact, we got an offer in about a week that was very close to asking price. Since we are out of state owners, Dave really went above and beyond to get things to closing, including shoveling snow!We ran into some difficulties moving our belongings out of there, and Dave even helped with that. He's a high-octane sales person, goes above and beyond the call of duty, and is also a nice guy. We highly recommend him!"


"I couldn't have asked for a better realtor. Seriously. Mr. Greenberg is very knowledgeable of the area and had answers to all my questions. He was always a phone call away if I needed anything. I strongly recommend. Thanks for being a part of our home buying process Dave!"


"I was referred to Dave by a a broker within his firm and I am so thankful. I have used Dave for both buying and selling in Summit county.

Dave had listed and sold a condo for me while I was out of state. He was working for me and it showed. Within 24 hours we had an offer at asking price. He took care of everything for me to make this process as easy as possible.

He is now in the process of helping me find my perfect dream home in the million dollar range and has been very patient with me. Took me to various sites within the county and I did not feel rushed or forced into anything. He understand this is a big purchase and has been very insightful and spend hours on the phone with me and the developers.

Dave is my go-to broker now in Summit County. With so many brokers in the county, it is important you go with the right one. Dave is that broker you want to know and work with . Both for selling and buying.

I highly recommend Dave Greenberg at Slifer Smith."

—Hanna Holtzberg

"Thank you Dave for the great job you did on my behalf. The sale of my condo less than a week after you listed it was fantastic ! But the sale of the second one after listing it only for a couple days was a terrific surprise. I guess your good contacts and your hard work to see everything come to complete and final closing was very much appreciated. Hope to work with you in the future. In the meantime wishing you all the best for 2017."
