★★★★★
"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." - Laura

★★★★★
"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." - Laura Neumann

★★★★★
"Will was absolutely fantastic to work with. He was there providing guidance from the initial steps of helping us figure out what we were looking for and could afford all of the way through the closing process. We were on a very tight time frame and had to travel out for a few days just to look at houses. We basically spent two full days back-to-back driving to and looking at different places. Once we finally picked our property, he helped us negotiate the purchase, managed the walk through and inspections while we were back out of town, and helped connect us with a local title and mortgage company. I would highly recommend him to anyone looking to buy or sell a home." - Matt Hansen

★★★★★
"William Grieg is an exceptional realtor. He approached us with enthusiasm and an assurance that he would be able to sell our home well above our market appraisal, and for 15% more than any other realtor thought possible. He created a beautiful video of our home, and our home sold within 2 weeks of its listing. Will is always on time, creative, savvy, and knows his market, helping to sell our home at the peak selling window in the 2021 real estate market. Start to finish, a very class and respectful man. " - Sherrie Marriner

★★★★★
"Will helped us buy our first home! We were so happy that he is now helping us buy our first investment property. Will walked us through all the details and steps in the buying process. He also introduced us to wonderful partners, like lenders, who have also become trusted advisors. Even the selling agent made sure to tell us that she also enjoyed working with him. Will doesn't just understand the real estate market, but also the macro environment to help you make informed decisions. He is kind but also firm when needed. He was always accessible and happy to chat. He was persistent and made sure everything went smoothly for us. We plan to continue to use him as our realtor." - Clio Castruccio

About William
William specializes in people.  Every person is unique and working with clients to understand how to best serve their needs (whether buying or selling) is what motivates him. Recognition of his true passion for working with people is what pushed William to earn his second masters degree from the University of Michigan, this time in Social Work with a concentration in interpersonal practice.  

During grad school, he founded and built a retail business that he sold when he moved to Boulder in 2014. Balancing a graduate degree, a business and training to be a professional triathlete gave William an appreciation for the importance of time management and hard work.  These experiences have helped inform his work in real estate and the respect he has for his clients time.

Since arriving in Boulder, Will and his wife have gone through the remodel process several times with varying scope which has provided a depth of insight into what it takes for his clients to turn a house into their home. When Will is not working on real estate or helping clients with the home search, he enjoys spending time with his family and their pup, often in the lake in their community - but only when it's warm enough!
