Anne Stutz - Secretary
Anne spent the majority of her adult life in Denver Colorado. December of 2015 she and her husband jumped off a 2000 mile cliff moving to Fort Myers. As a casual bike rider in Denver, Anne enjoyed 20+ mile weekend multi use path rides and short rides for for errands near her home. She quickly learned not all areas are bike friendly. While bicycling on a four-lane road in Fort Myers traveling in the bike lane the bike lane abruptly ended about a half a block from a major intersection. With no shoulder or sidewalk and being a casual rider this was terrifying.
That incident may have scared Anne away had it not been for finding like-minded people through social media. She now rides with local bike groups. After learning the hard way that Fort Myers does not have complete streets she applied for the board to help make southwest Florida more livable and safe for all.
Anne can be found daily somewhere between Venice to Marco Island working as a Territory Manager for OneCoast. Being on the water and biking with friends are her happiest places. She volunteered with United Way of Denver, National Alliance on Mental Illness of Colorado, Denver Heart Walk, and was a founding Board member of a High school Lacrosse Booster club.

Oscar Rattenborg - Director
My name is Oscar Rattenborg and I have always lead a double life of raising a family by working in IT, advising students, and teaching college biology and anatomy. The other part of my life has been building custom tandem bikes and promoting bicycle safety and access. Now that I am older, I can dedicate more time to advocacy.
What I am advocating for is safe environments for people to commute, recreate, and interact. We already have lots of space dedicated to cars and sparse public transit, but we need to do a better job of facilitating non-motorized connections between communities.
In addition to providing low cost transportation and safer places to travel, safer streets will allow for people to meet and interact. There is nothing more rewarding that going for a ride or walk and making new friends. You may not be immediately embraced or embrace all whom you meet, but over time, all are part of your community and you move from a “How’s it going” to more in-depth discussions.
Let’s meet in Streets Alive with people celebrating life and safely getting to and from life’s many engagements.
