I founded Mammoth Realty Group with the vision of creating a firm with the top professionals in the field - realtors with experience, ethics and unsurpassed professionalism. I believe that I have succeeded.
My team at Mammoth Realty Group boasts many years of valuable real estate experience, while offering the latest technology and advanced marketing services to aid the client in choosing the best property. I am a hands-on Broker-Owner, and have surrounded myself with an outstanding team of committed, knowledgeable people, each with particular strengths to grow Mammoth Realty Group.
As a full-time broker and top producer for over seventeen years, I have specialized in all areas of real estate including homes, condos, commercial, new developments and vacant land. I am an accomplished negotiator.
My clients would describe me as honest, extremely hardworking and very connected. I excel under pressure. I have been called a natural leader, not accepting numbers lower than 100%. Past clients would say that I work all the time and never quit. I go the distance to ensure that everyone is satisfied and happy. I do what needs to be done and more. My service doesn't come with boundaries; it's the enjoyable art of going beyond the necessary.
I have great intuition due to my many years in business. Often, I know which property to zero in on before a person finishes describing it. I do my homework and I believe in covering all possible bases. I am big on working in teams which creates team spirit, enthusiasm, and commitment.
The most important thing I can add to a situation is my personal service. I love to laugh with my clients and share their hopes, as well as their frustrations. First and foremost, I like to do business by "going by the heart."
I am what you might call a high-touch, technical traditionalist. I believe in mastering the latest computer technology to give my clients every possible advantage, which also means I can respond quickly to an opportunity and be better prepared along the way. At the same time, I will never lose touch of old-fashioned service.
I have a Bachelor of Science Degree from Woodbury University in Commercial and Residential Design. My unique ability to visualize a remodel or reconfigure a space with clients gives me an uncompromising level of service that very few realtors can provide to their potential sellers and buyers.
I'll say it simply: I love what I do. I am always available to answer any real estate questions. When you buy or sell a property with me, you'll see it. Real estate is my living. I work it, I breathe it.
I look forward to finding you that perfect dream mountain property.
