Jan Mitchell

Project Manager

Jan Alsobrook Mitchell joined the Youth Sports Alliance Team in 2010 as a JANS Winter Welcome volunteer which led to a paid staff position two years later.  In her current position writing grants and handling media, Jan draws on a 25-year career working in politics and non-profits.  As a newly minted graduate of the University of California, Berkeley, Jan packed up her pick-up truck and headed to Washington, DC to put her political science degree to use.  Her first paycheck came from the Democratic Leadership Council (DLC) chaired by then-Governor Bill Clinton, where she implemented a rigorous schedule of special events as well as writing briefings for Clinton and other elected officials from all levels of government.  Concurrent with much of her time at the DLC, Jan volunteered on Governor Clinton’s 1992 Presidential campaign where she knocked on doors up and down the Eastern Seaboard in support of his candidacy, managed fundraising events and worked in the ‘War Room.’

After her time at the DLC and a brief stint in on Capitol Hill working for Representative Steve Solarz (D-Brooklyn), Jan headed to the automotive industry where she worked as a registered lobbyist representing the industry to Congress, developing and implementing grass roots lobbying efforts, managing a Political Action Committee (PAC) and working with media to promote efforts in Washington and state legislatures. 

In 1999, Jan followed her Navy Pilot husband to the Netherlands for a 2 ½ year tour and then Jacksonville, Florida, where she juggled fundraising and writing jobs while raising their two children.  The move to Park City was a bid to escape the Florida heat. After trying out life as part-time residents for 18 months, Jan and her family left Florida on a humid 80-degree day and arrived to sub-zero temperatures.  They’ve never looked back, embracing trail running and skiing.  Jan originally hails from Sebastopol, California, in the Sonoma County wine country where she had a successful high school athletic career lettering 10 times (4 times in  track & field, 2 times in basketball, 4 times in cross-country).


Liz Myers

Brand Manager

Liz Craig Myers has been a part-time member of the YSA team since 2013, helping implement rebranding of the organization and generally making YSA look good. Originally from San Francisco, CA, she graduated from University of Wisconsin with a double major in Graphic Design and Art History, and worked in a small ad agency and a publishing house in Minneapolis before discovering Park City on a ski trip in 1997 and moving here with her husband in 2000 and working as an independent designer. A decade later, with two kids in the Park City School District and on several of the youth sports teams associated with YSA, it was an obvious fit for Liz to work with the organization that provides after school programs like Get Out & Play and funding for local youth winter sports.


Laurie Santoro

Executive Assistant

Laurie Santoro is a native Californian.  Raised in Morgan Hill, her childhood was spent walking through the foothill trails to the neighborhood pool, building tree forts and rope swings, searching for tadpoles, evening softball practices, and Saturday swim meets. After graduating Live Oak High School, she moved onto California State University, Fresno where she graduated with a BA in Communicative, Science, and Disorders.  Before diving into a career, Laurie felt the strong pull to explore a new life in the mountains and moved to Steamboat Springs, Colorado with her husband and their dog.  Steamboat brought a new lifestyle to the young couple and there they discovered mountain life.  After two wonderful years of working as a ski instructor, server, and counselor, family and careers pulled them back to the Bay Area of California. Laurie started work as the Service Manager for a national window and door company working with customers and technicians.  Throughout her nine years Laurie worked her way up through the company and lead the internal operations teams through major technological advances, database and software changes, product changes, and shifts in the workforce.  After having children Laurie’s desire to be at home with her two boys conflicted with the demands of her position as Operations Manager and she saw a great need for a Corporate Trainer in the quickly changing and growing company.  Laurie spent the last two years of her career training new and existing employees, coaching the Management team, improving employee satisfaction, and increasing profitability. As her boys got older, Laurie felt the need to be home with them full time.  In her spare time, Laurie volunteered in the school classroom, working on fundraising projects for education, volunteered as a reading and writing tutor for children with dyslexia, and countless hours of exposing her boys to their wonderful world.  Laurie shared her love for the mountains with her kids and after many years of weekend trips to the Sierras, Laurie and her family made the move to Park City, Utah where they now live full time.  Right in line with her passion for children and outdoor sports, Laurie began work with Youth Sports Alliance.  YSA strives to lead the community by providing access to sports and promoting active lifestyles for all local youth.  All the things Laurie loves to do is now right out her back door; hiking, biking, skiing, snowboarding, backpacking, exploring. Park City is providing Laurie with the things her dreams are made of, a happy and healthy family, involvement in the community, and new experiences to continually push herself to grow.
