Our Sioux Y Staff

Andrew Corley

Executive Director/CEO

Andy Corley is the CEO at the Sioux YMCA. Though he has been working for the Sioux YMCA for the last several years, he has been working within the Y movement for more than a decade. His YMCA story started off in Cape Cod, MA at a resident camp called Camp Burgess and Hayward. Of his commitment to the Y world and the Sioux YMCA, he says "It is amazing to see what an impact one organization can make in an area."

In his free time, Andy likes to stay active.  He can usually be spotted around town running or walking with his dogs, Mello and Murphy. Along with running, biking takes up a great deal of his free time.

Mark Barron

Sr Youth Development Director

Mark Barron comes all the way from South Carolina even though he is lacking a southern accent. He comes from a rather small family, just one brother and sister, with 3 nieces, a dog named Misha and a cat called Gremlin.


He has over a decade in experience working with kids in many different capacities. He started as a camp counselor at a YMCA in South Carolina and eventually worked his way up to being an assistant director and a camp director in his final years at that YMCA.


He hopes to do all he can to be a positive influence in the community and help make any time spent at the Sioux Y as fun and rewarding as possible for the local kids and teenagers.

Bri Summers

Volunteer Outreach Director

Brianna, or Bri, is excited to be joining the Sioux Y Team! She previously worked for Adventure Links in Clifton, Virginia and traveled to us with her dog, Kenai, and tortoise, Teton. She loves being outside and rock climbs, hikes, and adventures with the best of them. 

She has a giant heart, is very compassionate, and cares deeply about everyone she meets. She is excited to work with the teens and the staff, and to see what this next stop on her journey holds. 

Anthony Summers

Camp Director

Anthony is originally from Michigan but is traveling to South Dakota from Virginia. He travels with his two cats, Camper and Nova who are still trying to decide how they feel about the move. He is an avid outdoorsman and loves every new adventure that crosses his path.


He has worked for the American Youth Foundation, Boys and Girl's Club, Camp Bob, and YMCAs in Indiana, North Carolina, and Michigan. He is excited to bring all of his experiences to Camp here, and to learn as well! 

Dan Fraser

Development Officer

Dan comes from Edinburgh in Scotland. He has worked with youth in a variety of settings in different countries in the world for the last 10 years. During his time here at the Sioux YMCA, he has worked in multiple capacities. He has been down at camp, led wilderness canoe trips, and has been to all corners of the reservation for programs both big and small. 

Hanging out with Dan means getting a full dose of humor, a solid shoulder to lend a hand, and passion bigger than this world. 

Ben Elk Eagle

Cultural Advisor

Ben Elk Eagle has been working with the Sioux YMCA since the 70s. His favorite part about working with the Sioux Y is his involvement with the youth and adults in the communities of the Cheyenne Sioux Tribe Reservation as well as the surrounding reservations. He also enjoys having the ability to trael for meetings and working with the other Sioux YMCA staff members.

In his spare time Ben enjoys reading books, with one of his favorite books being Beyond Time. He also enjoys reading Native Newspapers. When Ben is not working or reading he likes to go for long walks.
