Joanne Ernstsen, a respected Denver icon in the real estate market, along with son Michael Ernstsen and award winning broker Jane Brennan, each bring a unique set of skills, background and knowledge to the newly formed Ernstsen/Brennan Team. This dynamic group combines their Denver real estate expertise, extensive industry resources, and cutting edge marketing research tools to offer their clients tangible results with exceptional personal service.

Joanne is a founder of the very successful LIV Towne & Country, which is now known as LIV Sotheby’s International Realty so she could get back to the part of the business she loves most…selling. A past President of the Denver Board of REALTORS, Joanne’s contacts in the industry are legendary. Her son, Michael a third generation real estate broker, learned from an early age about how to create a smooth and enjoyable real estate experience for the client.

Having three children of his own and growing up in the Greenwood Village area, Michael can relate to the needs of growing families, and is passionate about creating relationships with people. He has worked for over seven years matching the requirements of great families from all corners of the globe with the activities and schools around the Denver metro area. His background in technology and studies in International Affairs adds expertise in areas not found on other local teams.

Jane Brennan began her career in the 90’s and is an expert broker focused on Denver’s finer neighborhoods and suburbs. Having raised three children, now young adults, Jane understands and anticipates the many different phases of raising a family and how this can affect and change client real estate needs. Even-keeled, detail-oriented and aimed at exceeding goals, Jane provides clients with city or suburban options that solve housing challenges and meet family space and commuting goals. Experienced working with large corporate relocation departments, Jane is passionate about helping newcomers settle into the area. Jane has been recognized by her peers and the industry for her outstanding performance and service to her clients.

The Ernstsen/Brennan Team brings professionalism, integrity, and industry knowledge to today’s sophisticated real estate client. Their service-oriented approach and mastery of contract management gives busy clients the comfort of knowing their brokers can handle any or all portions of a transaction. Their employment of high-tech solutions for today’s real estate challenges without compromising the face-to-face service tough to find in today’s fast-paced, search-and-click world, offers a superior option for clients looking for top-tier real estate services.
