Megan is a rising senior at UNC-Chapel Hill, and will hopefully follow in her mother’s footsteps and pursue a career in medicine. Matthew is a rising sophomore at Peace University, studying game art and design. Dr. H is slowly, but surely, adjusting to her recent “empty nest”. She is proud of her ability to juggle her career and family. The Hutzenbuhlers enjoy traveling, especially cruising, scuba diving, and visiting National Parks. More recently, they have broadened their travel internationally and greatly enjoyed a trip to Africa two years ago, and Greece and Italy last summer. They are looking forward to visiting South America this summer. They have visited all fifty states. They are avid sports fans; especially fond of the Wolfpack, Panthers, Hurricanes, Jayhawks, and the Royals.
