Miikka, a USPTA P-1 professional, is one of Colorado’s top Open players. He finished No. 3 in the Men’s Open Singles in Colorado in 2013, was named High School Coach of the Year for the Northern Conference 2005-11, and in 2004 was named USPTA Intermountain Open player of the year. While playing for Azusa Pacific University, he received All-American honors.

Miikka has taught tennis for more than two decades and especially enjoys coaching young players. Before moving to the United States from his native Finland, he worked in the Finnish National Sports Institute, where he coached many top-ranked Finnish juniors. In Colorado, Miikka’s coaching has helped several nationally ranked junior players receive college scholarships to play at top universities. He sums up his teaching philosophy with what he calls the 3 Es: Entertainment, Exercise and Education.

Miikka’s languages also include German, Swedish and Finnish — and he welcomes opportunities to teach in them.
