Sincia Liu, Founder & Executive Director

For Sincia, Camp Tuku is the product of a long-lasting dream. Sincia was first introduced to a residential children’s summer camp at the age of 20, when she worked as a waterfront and bunk counselor at Trails End Camp (TEC) during her summer break while attending Rutgers University. She enjoyed the camp experience so much that she returned to TEC for two additional summers. Inspired by the bond and friendship that she built with the kids and the other counselors, Sincia vowed to someday start her own camp. After leading a successful 25-year career as an executive in the staffing and consulting business, she decided that it was time to pursue her other passion.

As someone who believes in the power of meditation and a healthy diet and lifestyle, Sincia’s vision for Camp Tuku combines the benefits of nature with an integrated program that cultivates a healthy mind, body, and heart. Her goal is to create a fun and joyful experience for campers while equipping them with tools that they can use to enrich their lives for years to come.

As a physician, Sincia’s husband, Tim, shares her passion for a healthy and adventurous lifestyle. They reside in Peoria, Arizona with their two children, Arwen and Anderson, their dogs, Sam and Mochi, and Puccini the cat. They can’t wait to embark on the Camp Tuku journey together!

Mark attended Luzerne County community college and received a degree in Hospitality and Culinary Arts Management and been working in the ever so changing service industry for over 7 years.  “Food is life, food sustains us, and most importantly, food is a gift that should be shared.”  Mark never tires of making delicious and nutritious food.
