Betsy Tietjen Gills Coach

Betsy (Bare) Tietjen, Gills Coach: Coach Betsy started swimming at 3 years old and has been coaching
since 2001. She attended Hawken upper school and swam with Jerry Holtrey. Betsy has been coaching
the Mayfield Middle school team since 2012 (minus one year at Hawken middle school). She has also

came to GLSS in June 2019. She loves working with the young swimmers and teaching them about the
ins and outs of the sport. Fundamentally, coaching swimming is about making kids excited about the
sport, by keeping it fun as well as giving them the tools to master the basics.

Betsy also teaches ELA and Social Studies to 6 th grade girls at the Hebrew Academy. When Betsy is not
working, she lives in Mayfield Hts. with her 17 year old daughter, Mareike, 15 year old son, Conor, 8 year
