Our Y Staff

Andrew Corley
Executive Director/CEO

Andy Corley (he/him) is the CEO and Executive Director 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
Chief of Staff

Mark Barron (he/him) 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.

Brittany Brooks
Associate Executive Director

"I am so excited to join the Y team! Growing up in Dupree, I can see the positive effects the Y has on our community. Andy, Mark, and the rest of the team have done an amazing job at making the YMCA of the Seven Council Fire thrive! I am excited to help continue growing the Y on the Cheyenne River Sioux Tribe communities and making a positive impact on our youths' lives. I love working with youth and adults and collaborating to make our area a safe place for people to be. I look forward to helping the Y continue in their efforts throughout the area."

Dani Parkison
Camp Director

Dani Parkison (she/her) comes to Camp Marrowbone from Colorado, but grew up in a fun-chaotic home schooling family of 7 in Kansas City. Dani has worked at a handful of YMCA camps across the country and has had the privilege of filling various camp staff roles, giving her a rainbow of experiences to add to the Camp Marrowbone family. Gaining knowledge, expanding traditions and building lasting friendships with campers and staff along the way has been Dani's favorite element and biggest motivator over her 9 year career in YMCA camping. In her free time Dani enjoys any kind of art project, camping and spending time outside, and being on the road.

A random fun fact she enjoys is that honey is the only food that does not rot! It is even okay for humans to eat a jar of honey after 3000 years! Thanks Bees!

Dani is so stoked to meet all the brave, amazing, smart, powerful, goofy Camp Marrowbone campers and staff! It is her hope to make a positive impact while learning and expanding her perspective on kids and camp and the community.

Kimberly Turney
Daycare Director

My name is Kimberly, I was born and raised in Pierre, SD recently moved to the reservation. I am an enrolled member of the Rosebud Sioux Tribe. I am the second youngest of 10 kids. I am a mother to two little boys who keep me on my toes. I attended college in Sioux Falls where I have an associates degree in media art but accidentally found passion in early childhood when I was working a part time job at a daycare. My early childhood career started almost 10 years ago working as an infant teacher, I have worked in every aspect involving daycare's, from everything to infant teacher, cook, transportation of children to now director. I have 4 years experience working for the Head Start Program where I obtained accreditation in preschool education. When I am not chasing kids, rocking babies, working cattle for our ranch or helping my husband flip houses for rentals, I am nose deep in a good book, gardening, or baking cookies!

Pete Stahlbrand
Family Camp Director

Pete Stahlbrand (He/Him) comes to the YMCA of the Seven Council Fires after a nomadic career at 11 camps in New Jersey, New York, Connecticut, Massachusetts, New Hampshire, Michigan, Missouri, and Victoria, Australia.  Pete first attended camp in the 5th grade and from a young age he strives in outdoor settings that brought him adventure and independence.  And as an adult, circumstances and opportunity always seemed to drag him right back to camp. 


Pete’s passion is to share the spirit of adventure with as many people as possible.  Whether bringing people together at Camp Marrowbone for a conference, outdoor education trip or summer camp experience, or loading up a bus for an exciting trip to a new city, Pete wants you to experience our world as a place of great opportunity for human connection and endless possibilities.  You’ll see Pete out and about at community events actively trying to embarrass his teenage son.  Feel free to let him know what adventure you want to see offered by the Y.


Mariah McLellan
Youth Development Director

My name is Mariah McLellan.  I was born and raised not far from Dupree and spent most of my life in the education field.  I am a member of the Cheyenne River Sioux tribe.  I recently took a leap of faith and joined the Y team and I could not be more happy and excited to see where this adventure takes me! Having 4 kids of my own, children are my passion. When I'm not at the Y, I can be found at a kids sporting event, cooking for a crowd, or spending time with my family!  I look forward to spending time with the kids at daycamp and continuing to learn and grow effectively with the Y team.

Frank Hernandez 
Kitchen Director

Hello Y family! My name is Frank Hernandez and I've been with the Dupree Y for 2 years.  Prior to working with the Y, I worked as a mentor for Aliso/Pico, a multi-purpose center working with inner city children in Los Angeles, California.  I then moved to Oregon where I began my culinary road.  I started as a donut fryer for a large grocery chain and moved my way up to cake decorating and eventually assistant bakery manager.  I then moved to ND where I worked for Prairie Knights casino and resort as a pastry chef. After Prairie Knights I had the pleasure of working with many chefs learning different skills not only in pastry arts but also in fine dining as well.  After many years of learning several cultures in food, I am proud to bring my skills to the YMCA meals on wheels food program and the youth feeding program during the summer and afterschool during the school year.  My goal is to offer our elders and youth a healthier way of eating and introduce different dishes from different countries that are healthy.
