Office Staff

Tina Persinger

Office Manager

It is both my pleasure and privilege to serve as the Office Manager for CAS.  I have been with the company since our debut in August 2011.  In January 2018 I began working full time at the Papillion office, giving me more of an opportunity to work directly with client families regarding services and insurance.  In my personal time I get to enjoy my children and grandchildren alongside my husband.  We love to walk, travel, attend local concerts/events and kayak.

I came onboard with CAS in April 2022 and have over 10 years billing experience in various medical specialties as well as certification in medical coding and auditing. I have a bachelor’s degree in international studies and Spanish from University of Nebraska at Omaha and an associate degree in Health Information Management. What intrigued me about CAS is their dedication to the development of kids and their support of their families. In my spare time I enjoy traveling, cooking, gardening, and spending time with my husband and three sons.

I have a passion for working with people and having their best interest in mind. In my early career, I achieved an Associate degree in Culinary Arts and Management at Metropolitan Community College.

After evaluating what I wanted for my future, I decided to pursue an Undergraduate degree at Bellevue University in Business, Management and Leadership.
