Shirley Thomas

I was born and raised in Alabama. I am a graduate of North Carolina Central University with a B.S. in Family and Consumer Sciences. I have also earned two Associates Degrees with certifications as a Medical Assistant and Occupational Therapy Assistant (OTA). I have worked in healthcare and in public and private education. I enjoy watching action movies and shows like CSI and NCIS, taking long walks, spending time with my husband and two beautiful daughters, and enjoying holidays with extended family. My favorite vacation destination is the beach, especially the Caribbean.

I graduated from Johnson C. Smith University in Charlotte, NC (J-C-S-U!!!) with a bachelors degree in Political Science, and I'm currently working on a masters degree in Public Administration from Strayer University. I have been a part of Duke Health since 2015, and my absolute favorite part of working for Duke is caring and assisting my patients with their healthcare needs. In my down time, I love spending time with my family and watching my children grow and flourish into little awesome people.

Missy Grizzle

I have worked in a OB-GYN office for 12 years. During that time, I took some billing classes and obtained my CPC license. I worked as a OB-GYN coder for 5 years and decided I wanted to have more patient contact, and that is why I decided to come to DukeWELL. I am a mom of two boys—one is a senior, and the other is in 8th grade. We keep very busy with sports and church.

Dawn Winstead-Bass

I started with Duke in March of 2019 as a Financial Care Counselor at Duke Eye Center. During that time, it was my responsibility to work with patients to resolve any financial barriers related to their healthcare. I am excited to be a part of the Duke PHMO team as a Care Coordinator. I have always had a passion to help people and my community. It’s exciting to be a part of a team that shares that same passion. In my spare time, I enjoy baking, binge watching shows, and spending time with my family.
