About me

While helping my clients go through the process of adoption in the most expeditious and painless manner possible is very important to me, so, too, is living a healthy, balanced life.  I work hard and play hard.  I enjoy hiking, stand-up paddle boarding, kayaking and biking.   I love to travel and have been blessed with the opportunity to see various parts of the world.  I like to listen to and make music, too, by playing the ukulele and guitar.  It is so much fun to get together with friends, play and sing while enjoying good home-cooked food.  Life doesn't get much better than that.
