Jennifer Mount
Principal Broker
As the founding partner of Legacy Realty Advisors and the Managing Broker. I bring 23 years of experience to the table helping over 500 families achieve their Real Estate Goals. I am a true Tulsa native born and raised here and fun fact I have only lived in a 9 mile radius my entire life. I am a mom of 2 and 2 years ago became a proud grandma. I value: my faith, family, health and career. In my free time I love to do most anything outside, especially run, bike and golf. I love serving my community in many capacities from Church to feeding the homeless to encouraging my team. I participate in marathons, triathlons and even have the opportunity to push disabled people in various races around town. I love to learn and challenge myself and see growth both as a person and a professional. I love our Real Estate market and helping people achieve their Real Estate goals is the icing on the cake of my blessed life.
