A passion for real estate…with that passion, I will represent you with 100% of your interests in mind, while educating you throughout the process. With my 35-year sales and finance background and 45 years of living in the Boulder/Louisville area, I will utilize my resources and negotiate the best possible price, while making your real estate transaction fun and exciting, not frustrating and stressful. I offer extensive experience, knowledge, integrity and diligence.
I graduated from Fairview High School in Boulder with honors in 1984. After high school I graduated from University of California, San Diego suma cum laude, top 1% of my graduating class in 1988, with an economics degree and double minored in exercise physiology and psychology. I then returned to Colorado, because this is where I truly love to live for endless reasons, and also have the pleasure to be close to my family that also lives in the Boulder area.
I am honored to be a top volume and production realtor for the last 15 years! I have sold over $100 million in real estate throughout my career! Live West Realty also had a record breaking sales year and has close to 40 agents. Live West Realty has a solid foundation and reputation for more than twenty years. Live West Realty concentrates on customer service and professionalism.
I was also recognized as 5280 Magazine’s Top Real Estate Agent. This award was based on total production and customer service from my clients, peers, and real estate experts!
I work hard to make your real estate experience memorable, enjoyable and stress free. I have also created a large personal network and excellent rapport with my personal contacts, business, and established real estate brokers in the area and will integrate my relationships when guiding you in either purchasing your new dream home or marketing your home.

Mary Siefert
I have worked with many Realtors over the years, and I would rather work with Mary than any other! She knows the market and how to achieve the best outcome for her clients. She understood what I was looking for right away and was very thorough, but she didn’t waste my time showing me properties that didn’t meet my description — always considerate, energetic and available to answer any questions — I can’t speak highly enough!
Maya Rogers
Mary was awesome in every way. She understood our needs both when selling and buying and got me moved within my timeline. She made it feel like it was personal to her. I would work with her again and refer her without hesitation!
Sarah Skolnick
Mary makes things happen! She goes the extra mile for her clients, whether it’s arranging for a handyman, cleaning up or staging. Want to see property at the last minute….. Mary will be there for you. She is thorough in everything that she does and I can count on her to come through. She is honest, reputable, and knows the market. Mary is the Best!
Colette Valette
I highly recommend Mary Siefert for your Boulder County Real Estate purchase! Mary and I have worked together for my search and purchase of three properties in Boulder. She is super responsive, flexible on short notice and forthcoming with her advise. Bonus…Mary has a great sense of humor and you’ll have some good laughs along the way
Michael Ekegren
Few Realtors bring knowledge, professionalism, kindness, and charisma together like Mary. Our office regularly works with Mary and all we see are raving fans after each closing.

Mary Siefert and I have been working together for over 10 years now. I like working with her because she is the kind of Realtor that really protects here clients, and is there for them every step of the way. She will go to any lengths to get things done and make sure everything happens the way it needs to. Mary’s ease of turning clients into friends has always been impressive to me as well. She is just that kind of person! I am always honored when we get to work together on a Home Purchase, and it is just a fact that my clients will be very happy with her.
Kevin Teel
Mary was an absolute rock star in helping us find our first home! We changed our minds a lot throughout the process, but Mary was super flexible and just rolled with the punches. She met us out in the mountains to look at houses, as well as all over Denver and the northern suburbs, before we finally found the perfect home in Longmont. She had some amazing advice for putting together our offer and we ended up winning out over 10 other competing offers! It’s a crazy market out there, but with Mary we always felt taken care of and listened to. We couldn’t be happier with our new home, thank you Mary!
Lynette Schwanger
Mary is very friendly and professional. The best thing I would say about her is she has your best interest at heart and not just a Realtor trying to make a sale. I would highly recommended her
Stan Martinez
On paper, Mary is at the top of her class. In person, she’s become a friend, as eager and excited about our new home as we are. Thank you, Mary, for your patience and expertise as we settle into our new home base!
