Our team approach gives our clients a high level of personal service, resulting in a smooth and stress-free real estate experience. Our vast experience and competency, coupled with our enthusiasm and humor always keeps our clients smiling!
We are your "Realtors® for Life" and help a wide variety of clients in all stages of their life, including relocating families who are new to the area, first-time homebuyers, growing families buying a larger home, and people who are looking to downsize. Our team concept allows us to cover a much larger geographic area than most realtors, so it is truly "one-stop" shopping and service with Mary Lee & Jeff Shaffer!
We specialize in single-family residences, condominiums, townhomes and new construction within the cities of Seattle, Bellevue, Mercer Island, Newcastle, Renton, Kirkland, Bothell, Woodinville, Redmond, Issaquah, and Sammamish. We keep current on market trends in Seattle and the Eastside and are knowledgeable about the local schools and community resources each area has to offer.
We live in Bellevue and really enjoy the variety of community and outdoor activities the Puget Sound area offers. In our off-time we enjoy boating, traveling and enjoying quality time with family and friends.
Let us put our proven real estate skills and experience to work for you!


We believe that true success comes from doing the right things for the right reasons.
