Today is a very special day at CAC as we celebrate our own Kristie Tatum, one of the true cornerstones of our organization.

Kristie is retiring after an incredible 47 years of service, dedication, and heart. Over nearly five decades, she has worn many hats, supported countless patients and teammates, and helped shape CAC into the practice it is today. Her knowledge, work ethic, and steady presence have made a lasting impact that simply can’t be measured.

As if that weren’t special enough, Kristie is also retiring on her birthday, making today a celebration in every sense of the word. 🎉🎂

Kristie, thank you for your loyalty, your compassion, and your commitment to excellence. You leave behind a legacy that will live on for years to come, and you will be deeply missed by all of us.

Please join us in wishing Kristie a happy birthday, a happy retirement, and the very best as she begins this next chapter.
