Learn More About Me!

Hello Visitors and Soon-To-Be Friends,

I love long distance rides on my motorcycle. Traveling is a large enjoyment of mine. I have traveled to India, China, Japan, and New Zealand. In fact, I used to be an instructor for the Motorcycle Safely Foundation.

Educated as a science teacher, I’ve taught in public schools in Ft. Lauderdale, Chicago, and Des Moines. I was a Sunday school teacher at my church, too. I am defiantly looking forward to working on science projects with my 7 grandchildren. Facetime has really helped me stay connected with my little munchkins.

I am a huge Downton Abby fan and always go to the True and False Festival, here, in Columbia MO. I enjoy the Star Wars series and am known for using Yoda’s words of wisdom, “Don’t Try, Do” for self-motivation. In my spare time, I listen to the Happy Potter, Lord of the Ring, and Star Wars soundtracks. All in all, I love a good motorcycle ride with my family and/or friends in a beautiful landscape listening to epic soundtracks. Now that you know a little about me, I look forward to learning a little about you. Contact me! Let’s talk!

Professional Service… with a personal touch.

I aspire to grow my business through referrals by providing the highest levels of service and always exceeding my client's expectations.
My Statistics:
* Top 50 Agents in Columbia MO for over 20 years
* Average over 20 transitions per year, equaling over 500 transactions in my lifetime!
* Expert negotiation skills. With each transaction, I typically negotiate with 10 different individuals; that’s over 5000 different personalities and individuals I’ve negotiated with in my career.
I know how to look out for my client’s best interests.
* Of the 500 homes I’ve sold, I’ve personally toured and viewed over 6000 homes in Columbia.
I know the neighborhood.
* I’ve spent over 17,000 hours working directly on closing transitions for my clients.
That makes me a full time Master in my profession.
I love what I do and measure my success with my clients’ satisfaction with my services.
I take pride in myself on being patient and caring for my clients. I treat them like my own family.
My promise to you is to listen carefully to what you say so I understand your objectives and concerns.
