Former Contributors


Cristina joined us as Executive Director in 2018, after seven years in Norway immersing herself in orienteering culture. She has been involved with orienteering, maps, and navigation for as long as she can remember: first as a navigational assistant to her dad while driving, then as a geoscience student, combat search and rescue navigator in the Air Force, and finally as a top level orienteer representing the US at the World Orienteering Championships and World Ski Orienteering Championships. Cristina has also coached groups ranging from 8 year-old beginners up to Junior and Senior US Teams and spent several years in the classroom teaching middle school, high school, and college students. She is infectiously enthusiastic about orienteering and its potential as a lifelong activity that helps develop confidence, decision-making, and map reading skills. 



Evalin began working with Navigation Games in June 2018, coaching middle school teams and teaching community school classes. She studied sports management with a concentration in exercise science and is excited to use what she learned in working with Navigation Games. Evalin was also a member of the national junior, university, and senior teams multiple times and represented the US internationally. Having grown up in the sport of orienteering she is excited to bring the sport to kids in Cambridge with the hopes that more kids will enjoy participating.

He joined Navigation Games in May of 2018 and is bringing an environmental outlook to our programs. When he's not busy with our community school classes, he's also working as an EMT.

Maiken came from Norway to volunteer with Navigation Games during the summer of 2018. She studies Sports Management and her knowledge was very helpful during the youth summer program. Maiken has been orienteering for several years in Norway and has done a lot of event management for the Norwegian O Festivalen, and volunteered with the organizing committee for JWOC and WOC. She also enjoys coaching children.

Altough specializing in bike orienteering, both Tomas and Marie still participate in Foot-O regularly. 



Violeta is on the national orienteering team of Spain, and she brought her passion to Cambridge to share with our students. In Spain, she taught orienteering to childrne in extra-curriculuar classes, and worked as ain instructor in a summer orienteering camp called "Muyer y Deporte" (Women and Sport), in which girls and women of all ages with different levels of knowledge of the sport want to learn how to orienteer or just improve their technical skills. In Cambridge, Violeta taught and coached many children. She also made an awesome video about her time in the United States.



Juan Manuel ("Juanma") Merida teaches orienteering and coaches sports in Spain. He is perhaps best known for organizing the Madrid Orienteering Olympics - a large event for schoolchildren held annually in a large park in the city of Madrid. The goal of the program is to give children the opportunity to try out the sport, and to make sure they have a great time doing so. Any school can participate, and each year they have more than 1000 children ranging in age from 9 to 16.  While he was here, Juanma coached middle school teams, taught children in grades K-5, and helped with our high school athletes. Juanma came to us thanks to his friendship with USA Junior Coach Greg Ahlswede.  Thanks, Greg!
