Personal Interests

We love spending our vacations skiing in Colorado and with years of experience, I am finally getting better. I love to draw and paint, water color and India Ink are my favorite mediums. I find playing Beethoven and Mozart on the piano very relaxing. I enjoy reading and learning French and Italian, I found it gives me an excuse to travel and enjoy Europe. I love to cook and bake Julia Child French Pastry.


We have 3 children and 4 grandchildren that all live locally. I have 4 cats that provide lots of entertainment and cuddles.
