Meet our billers
Sara - Lead Biller
I have worked in healthcare for 19 years, both as a sonographer and now as a biller. I am originally from Pleasant Hill, IA but moved across the country to McDonough, GA in 2019 to be closer to my husband's family. I have been married to my husband, Joel for 19 years and together we have 2 children, Hannah and Noah. We also have 3 crazy geriatric dogs; we joke we run a nursing home for dogs. I am fortunate enough to do this job from home so I can homeschool my children. In what spare time I have, I enjoy reading and refinishing old furniture.
Anne - Biller
I was born and raised in Madison, WI and moved to Minnesota to attend the University of Minnesota - Twin Cities. I graduated in 2007 with a degree in Family Social Science with an emphasis on Addiction Studies. I have been in and around various health care systems for the greater part of my adulthood, and am proud to be a part of the Guardian Billing team.
Krissy - Biller
I was born and raised in NY but moved to South Carolina in 2016 in search of warmer weather! I graduated in 2001 with a degree in Medical Billing and have been exposed to a number of specialities throughout my career.
When I’m not at work, you can find me in the car headed to the sports event of the day with my family. I have an Australian Shepard named Milo, and he’s my favorite buddy. When I have time to myself, I’ll either be watching reality tv or reading.
Nancy - Biller
I have worked in the medical billing field for over 20 years. I enjoy the challenges of solving the problems and helping my providers and clients with the issues that can come up within the medical insurance world. I worked for a major health insurance company for 5 years before starting my own medical billing service and became a certified biller. I have billed for providers in a wide array of practices from neurology to physical therapy.
I grew up in northern California where my father was stationed in the United States Air Force. My family moved in 2020 to Oklahoma to embrace our Native American ancestry and culture as well as to be closer to family. In my free time I am out kayak fishing and enjoying nature.
Jessie - Biller
I am originally from the Northern Virginia area and just recently moved to Jacksonville, FL. I bring 15 years of experience in the medical and billing field to my position at Guardian Billing. I enjoy exploring new areas with my two daughters, and we love doing anything outdoors.
Kristina - Biller
Born and raised in Texas, I now call wherever the Air Force sends us home. I have 10 years of medical billing experience and am excited to continue to learn more with Guardian now.
In my free time I like to quilt, garden, and spend time with my husband and cats.
Nicole - Biller
I was born and raised in South Florida and relocated to North Florida promptly after starting my family. I have been married to my husband, Zachary, for 10 years, and we have two children, Zachary and Zoey. I sing in my church choir and love crocheting, doing paint-by-numbers and diamond painting. I completed school in 2015 with my Certified Professional Coder Certification and have billed for several different professional specialties since then. I am so excited to have joined the Guardian family!
Trinity - Biller
I started working for Guardian Billing in 2023. I am proud to work with such a great company and team! I was born and raised in Minnesota. I love all the seasons! I also coach competitive cheerleading. In my free time I like to work out, travel and hang out with my family!
