Cornerstone Cooperative

Lisa Serrano

Lisa has been homeschooling her 3 children since her oldest was about to start school 10 years ago and is so thankful God has called her to do so. Before moving to TN, Lisa and Armando had been involved in ministry and pastoral care for 15 years leading and helping marriages and serving families. They believe strongly in church community and being real. As a family they enjoy game nights, hiking and look forward to their weekly family movie night and watching football and basketball when in season. Despite the mess and challenges of having a fixer upper home with tons of projects going on at once, they love having people in their home to share a meal and to fellowship. The family has a goal to search for the best burger in Tennessee but think their dads burgers are the best! She’s her husbands biggest fan and her greatest joy is praying over and ministering to her children. Lisa loves her morning coffee, serving, reading, making her home cozy and peaceful, tending to their chickens, growing their own food and recently, cooking! 

Kelly Knapp

A native of WNY, Kelly has been married to Jeff for almost 20 years. They officially became a homeschooling family in 2011, and since relocating to East TN five years ago, have been blessed with a flourishing homeschool community at both Cornerstone Cooperative and at their beloved church, Calvary Chapel Knoxville. The Knapps live in Maryville with Bentley, their golden retriever, and 3 unique cats who are full of personality. Together they enjoy playing games, snuggling, watching football, and hosting gatherings in their home. Kelly loves to read, cook, bake, write, and decorate, and considers it her greatest joy to invest in her children: Jeffery, John, Katherine, and Margaret. Serving local homeschool families and founding Cornerstone together with Elena has been a ministry highlight, and a catalyst for her personal and spiritual growth these last few years, and she considers it a privilege and a blessing to serve this community. Go Bills!

Tiffany McCall

Tiffany and her husband Rowdy have two daughters, Adelynn, and Anna, who have been homeschooled all their lives. The McCalls attend Calvary Chapel Knoxville, and they own and operate a local family asphalt business. Tiffany serves as the secretary on the Cornerstone board but beyond her administrative duties, she enjoys teaching science classes at Cornerstone as well as assisting other teachers in their classes, and loves all of her students! When not paving driveways or working on spreadsheets, the McCalls can be found camping, traveling, swimming, and enjoying fun family game nights.

Elena Nelson

Elena, wife to Erik and homeschool mom of 3, began homeschooling over a decade ago after leaving the banking industry. Throughout their homeschooling journey, the Lord has grown a passion in them for global missions and through this, led them to live in London for a year to open a cafe associated with a church. When they returned, God made a way for Elena to help start this amazing homeschool community we call Cornerstone Cooperative. You can find the Nelsons serving at their church, as well as out and about as they use their entrepreneurial skills to connect with and serve the people of Blount County through one of Maryville’s beloved food trucks. When not serving, cooking on her truck, or teaching, you can find Elena floating in the sun on Tellico Lake.
