Wolfgang Dittrich

Wolfgang swam his first competitive swim race in 1967, and competed in the 1980 and 1984 Olympic Swim Trials. He was a member of the German Junior National Swim Team and German National Swim Team. In 1984 Wolfgang turned his athletic focus to triathlons, competing and achieving world class rankings as a professional tri-athlete until 2000.

Wolfgang has been a certified swim coach since 1982. He is the Head Coach and Founder of Flatiron Swimming established in 2009. His extensive coaching background includes ten years coaching triathlon training camps with swim-specific sessions, coaching the Poseidon Swim Team in 2002 (a junior high & high school national/elite level athletes summer program), a Masters Swim Coach at several pools in the Boulder area, and coaching private individual lessons for all levels including beginners, tri-athletes,  pent-athletes, teens, adults, and babies.

Wolfgang coaches all aspects of swimming - stroke, kick, breathing, diving, stretching, competition, and relaxation/focus. His philosophy is that swimming is for everyone, preferring persuasion rather than demands to get the most out of all athletes he coaches.

Wolfgang's vision is for Flatiron Swimming to be Boulder's premier swim team for all levels of swimming.

Tricia Butcher

Tricia started coaching swimming as an undergraduate assistant at North Carolina State University – assisting with both the men’s and women’s programs. After graduating with a Masters degree in Food Science and Biochemistry minor, she moved to Colorado. She worked for 5 years in the food and nutritional supplement industries in both research and product development before starting a family. Today her three daughters are all actively involved in swimming and her own love for swimming drew her back to the sport. She began coaching with Wolfgang Dittrich in January 2009 and loves working with kids of all ages.

Tricia began her own competitive swimming career at age 10 in Durban, South Africa. She swam with the Pinetown Otters and North Durban swim clubs while growing up in South Africa. At age 15 she broke the South African national record in the 800m freestyle and went on to also break the 400m and 200m freestyle national records. She was a member of the South African National swim team and won numerous national titles. At age 18 she left for the States on a full ride athletic scholarship to North Carolina State University. While at NC State she won four Atlantic Coast Conference (ACC) titles (three in the mile and one in the 500 yards freestyle). Her junior year, she placed 10th in the mile at the Division 1 NCAA Championships. She was a Collegiate Athletic and Academic All-American. She swam in the British Olympic trials in 1984, placing 3rd in the 800m freestyle.
