Meet Your Executive Team

Casey Lille 1 Source Insurance Group

Casey Lillie | CEO


Look for the center of the action, and that’s where you’ll find Casey Lillie. His vision, can-do attitude, and hands-on approach have brought him great professional success and personal satisfaction. Casey excels in creating opportunities for others to succeed. His experience grants him unique insight into the upper reaches of Medicare, Life and Annuity marketing and sales strategy. When he’s not consulting with an agency principal on lead generation or the details of a 401k rollover, there’s no telling what Casey is up to. He could be hunting a bear, deep-sea fishing, enjoying a building project, teaching his kids a new skill, or planning his family’s next great travel adventure.

Denise Lille 1 Source Insurance Group

Denise Lillie | CFO


No detail gets past Denise Lillie- she doesn’t miss a beat or overlook an opportunity to help agents grow their business in a compliant way. Denise is highly skilled in managing appointment setting teams and long-term client retention strategies. The time she invests each sales season compiling plan data and generating market-specific action plans pays off every year. Put a cup of coffee in her hand, and she can complete any project in an accurate and timely manner. Denise loves adventurous travel, hanging out at the pool and spending time with her family… especially on days when her alma matter’s UT Vols look alive on the ballfield!

Lance Edwards 1 Source Insurance Group

Lance Evans | Insurance Specialist Manager


Steady. Trustworthy. Dependable. Lance Evans. Homegrown in the TriCities, Lance developed a strong moral character and a passion to help others better their circumstances.

When you seek his advice, he’ll deliberate on the big picture and ask questions to get each small detail right before providing a practical, achievable solution. Lance’s thoughtfulness and loyalty shines through in every aspect of his life. When he’s not helping others, Lance loves to enjoy a good meal with his family and indulge in as many sweets as his wife Amy will allow. She may succeed in shipping him off to the gym to stay fit, but Lance prefers to set sail with her on a cruise ship. He loves to reminisce about past trips and is always seeking or packing for his next great adventure. If you’re looking for a lifelong friend, relax, talk travel… and sneak Lance some sweets!
