In 1992, Engle was named the Rolex/ National Grand Prix League Rider of the Year, a feat she repeated in 1993. In 1999, Engle rode Hidden Creek's Alvaretto to the Team Silver medal at the Pan American Games in Winnipeg, Canada. At the 2000 Sydney Olympic Games, Engle was the highest placed woman and the highest placed U.S. rider in the individual competition riding Hidden Creek's Perin to a 10th place tie in the Individual Show Jumping competition and a sixth place Team finish. Engle has so many "firsts" and records in her career; they are too numerous to mention.

Engle has persevered through serious injuries including a crushed leg in 1990, which she followed with five major AGA wins in 1991. She suffered a broken hip when a horse fell on her in 2004. Just three months later, riding her Olympic mount, Hidden Creek's Perin, Engle beat a field of 26 entries that included eight Olympians, to win the $100,000 Cosequin Invitational Grand Prix in Culpeper, Virginia. She came back with a vengeance to successfully compete in 2005, and in 2006 she has led the World Cup standings all year. Her performances on the U.S. Team as part of the 2006 Samsung Super League tour have led to an Individual win in Aachen as well as a team second in the Nations Cup there.

Engle lives in Wellington, Florida, with her husband, Dr. Steve Engle, and is well-known for her incredible sense of humor.
