Alien In-Line was started in 1994 by four ice speed skaters that used in-line skating as a summer training method and had passion for teaching. In-line skating was booming across North America and everyone desired to learn how to do this exciting novel sport that offered a fun new way to move on wheels. At that time, Alien taught in some of Calgary's health clubs and fitness centres with its main clientele being recreational, fitness programs, and individual lessons.

In 1995, Mark Greenwald and Pat Seltsam, two of the original four founders, incorporated the company and together purchased the first fleet of school programs skates. Shortly afterward Alien began piloting programs in Calgary schools. Over the next fifteen years, under Pat Seltsam's entrepreneurial guidance and Mark Greenwald's teaching and programming skills, Alien prospered and grew into the largest organized school skating program in North America. Today, Alien In-Line teaches kids to skate in over 250 schools in Calgary and the province of Alberta reaching over 100,000 kids annually. Alien In-Line has also done pilot programs in Salt Lake City, USA and Vancouver, BC, Canada.

Mark Greenwald

Mark is one of the founding members of Alien In-Line. Mark was born in Chicago Illinois and visited Calgary, Alien's home base for the first time in 1986 while competing in the North American Speed Skating Championships. He would return two years later to compete in the 1988 Winter Olympic Games in long track speed skating. During the summer months, Mark raced on in-line skates for Team “Speed Specific”; a team made up of members of the US National Speed Skating Team (ice) and in 1991 was part of the National Champion Team Pursuit squad, earning this achievement at the 1st International In-Line Skating Association (IISA) National Championships held in Irvine, California. He also raced on the Rollerblades series circuit across North America with that team in the early 1990’s, and later with Pro Team K2 through 1994.

Following a role with a speed skating club coaching position (Matsqui Blades) in Abbotsford, BC, Canada in 1992/1993, Mark returned to Calgary to finish his undergraduate degree and also began teaching in-line skating. He became certified as a Level I and II instructor, and eventually an Instructor Examiner for the IISA, teaching and certifying over 30 instructors in Alberta between 1999 and 2006. Mark maintains contacts in the skating industry and with the eventual successor of the IISA, Skate Instructors Association (Skate/IA).

Mark also earned his MSc. in Kinesiology in 2000 and worked at the Calgary Olympic Oval for 17 years serving in roles as a coach, Program Manager/Director of Sport, and eventual Director of the Oval through 2009. He was an architect of the very successful high performance sport model at the Olympic Oval, contributing to over 20 Olympic medals for Canada in the sports of long and short track speed skating and women's ice hockey through the 1998 to 2006 Olympic Games.

Dallas Kurtz — Dallas Kurtz is from Calgary, AB and has been in-line skating for 16 years. He began teaching with Alien In-Line in 2002. Dallas's favorite skill to teach is the Touch Down which is a trick that kids can really challenge themselves with. His favorite place to skate is on the streets of Calgary, but he also enjoys Calgary's skateparks. In Dallas's spare time he enjoys even more rollerblading and playing pool. His teaching tip to remember is to always bend your knees and keep your feet together while doing the heel brake stop.
