Mark Sheldon & Didi Von Deck

Mark Sheldon & Didi von Deck joined the professional ranks in October 2005. Before that, they were among the most experienced and respected amateur instructors in the United States. They have coached and lectured extensively on the university circuit. Mark has coached the MIT ballroom dance team to great competitive success for over 5 years and has also coached at Harvard and Boston Universities. They are known for their good humor and their clear and engaging teaching style.

Competitively, they have represented the US at 7 Amateur and Senior World Championships and at the World Games, they are 3-time Open British Senior finalists (the only US couple ever to make that final), International finalists, and 5-time undefeated US Senior Champions.

As performers, Mark and Didi are known for their easy movement, elegance, and sensitive musical interpretation. They also maintain full-time non-dance careers: Didi is an orthopedic surgeon and Mark is a visiting assistant professor of computer science at Wellesley College.
