Unique things about me

I recently started kayaking and love it! I’ll go out on the Potomac River and float for hours while fishing, it’s truly relaxing. I also like taking my dogs to the river and seeing them enjoy the water.

When I am not at work

I love the outdoors. You can find me kayaking, hiking, golfing, or taking my dogs to the dog park. Every summer I spend a week at the beach with my extended family of 40 or so. I also enjoy music. I am currently learning how to play the guitar, but my oldest daughter plays guitar, my son plays drums and my youngest daughter plays the keyboard.
