I moved back to Maryland from Nevada in 2018 and have really enjoyed all that the area has to offer. I love the seasons. I lived here and finished college at UMD in the late 80’s before moving to Nevada through the Air Force.


Outside of work I enjoy spending time with friends and visiting local sites with guests from out of town. My biggest passions are my dog and my horse.
