Katie Hoskinson

Katie McNamara

Executive Director

A passionate relationship builder, Katie specializes in collaborating for change. With creative enthusiasm and an ability to steward vision to action, Katie excels at bringing many voices and thoughts together.

After graduating from St. Lawrence University, Katie was drawn to the non-profit sector and volunteerism. Katie served as a full-time AmeriCorps volunteer at Teton Science Schools, with the focus of building organizational capacity for STEM literacy. Since 2013, Katie has focused on building collaborative relationships with non-profit and government organizations through the AmeriCorps program, combining her passion for science, education and community development. Katie has mentored over 150 AmeriCorps volunteers and instructors in their development as educators, leaders and engaged community members and facilitated place-based education programming for schools and organizations across the United States. These experiences left her with a deep appreciation for this place and a commitment to building a more connected and healthy community.

Katie grew up learning to swim at her local rural outdoor pool and fell in love with competitive swimming and diving at an early age. Katie believes all people should have the ability to access the essential life skill of swimming and the opportunities it provides to improve their quality of life. Katie believes an aquatic facility in Teton Valley has the ability to be the heart of our community, where an infant experiences water for the first time, a child feels pride after their first race, a senior citizen forms meaningful connections with others and all learn to enjoy water safely. Here, our community in all of its identities, challenges, and passions is brought together. Katie believes collectively we can work to create a more vibrant community through the innovative design of a world-class aquatic facility and implementation of impactful programming.

Katie enjoys swimming, skiing, biking, competing in triathlons, floating the Teton and exploring our public lands with her dog Tupper and husband Billy.

Hannah Wells

Executive Assistant

Hannah Van Arsdell was brought to Teton Valley as a founding member and owner of Sego Ski Company, but really, to ski. Since settling in this beautiful valley, she joined the team at Teton Regional Land Trust as their Marketing and Outreach Coordinator. She gained experience with marketing, grant writing, fundraising, wrangling volunteers, and got to know the landscape of Eastern Idaho. Currently, she serves on the board of Teton County Idaho Search and Rescue.

Hannah is passionate about this project because of the incredible value and wellness that an aquatics center will bring to our community. Hannah has been recovering from multiple back surgeries and nerve damage, which has stopped her from skiing as well as many of the outdoor activities she enjoys altogether. She feels this project will benefit those like her that could enhance their recovery and recreational opportunities with access to a therapy pool and a public lap pool. Hannah also grew up swimming competitively, and appreciates the experience of learning how to swim and the gains swimming has brought to her. She sees the undeniable benefit everyone in the valley will have with the opportunity of having an aquatics center here.

In being involved with this project, she hopes to give back to this amazing place we call home.

Fielding Essensa

Board Member

I grew up in New Hampshire prior to moving to the area 12 years ago. While growing up there, summer days on the beach turned into competitive swimming in the winter starting when I was 9 years old. Summer jobs as a lifeguard and swim instructor followed as well through college, where I oversaw the town pool every summer. I graduated from St. Lawrence University in 2007 with a degree in Economics, where I met my wife Kim. Needing to learn to snowboard in order to keep up at Whiteface, I quickly fell in love with water in snow form all over again. I relocated here for a ski season and never left.

After working in various accounting positions throughout the valley and Jackson, I started my own custom knife company two years ago, TC Cutlery. I specialize in forged stainless steel kitchen cutlery.

Having spent the majority of my life in the water, bringing that joy to Teton Valley is a natural fit. I believe every child should learn to swim regardless of means, and get to enjoy the benefits of swimming and other aquatic pursuits. I am excited to be a part of TVA and hope to assist in seeing this project through, giving back to the community we love and call home.

Barbara Beller

Board Member

I was born and raised in Saginaw Michigan spending every summer at the family cottage on Au Sable Lake swimming, skiing, fishing and boating. Water was literally all around me. Some of my earliest memories included swimming lessons at the YMCA with neighborhood friends and my two brothers. I was on the swim team in High School and loved to swim laps to improve my strength and endurance.

I earned a degree from Michigan Technological University in Civil Engineering with an emphasis in Environmental Engineering. Following graduation, I worked in Denver Colorado and Salt Lake City Utah before moving to Idaho. I worked for the Department of Energy at the Idaho National Laboratory as a project manager in the Spent Nuclear Fuel Program from 1987 through 2014. I received a MS in Technical Management from University of Idaho shortly after moving to Idaho.

My husband John and I have three children. They benefited from swim lessons and were on swim teams in Idaho Falls. I became a stroke and turn judge to support the Piranhas swim team.

My husband and his family have skied and hiked in the Tetons all their lives. I am a recent transplant to Idaho, 32 years ago. We purchased a home in Driggs in 2011, and moved permanently in 2018. I am excited to be a part of the Teton Valley Aquatics team to bring year-round swimming to the Teton Valley.
