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 DukeWELL team as a Senior 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 2024, I earned a Bachelor of Science in Business Administration from the Bryan School of Business and Economics at UNC Greensboro.

Latoya Jones

I was born and raised in Durham, NC, and I am a mother of three boys. I enjoy meeting and working with people from all over. Experiencing the loss of both of my parents within the past year inspired me to become an advocate and voice for patients within the health care system.

​I am originally from Guatemala, Centroamérica​. I am bilingual (Spanish-English). I came to the United States when I as 21 years old with my family. I have 3 kids and always tried to participate in their school activities. Now, they are 23, 21, and 16 years old. I love to play sports and be active as well as my three kids. I love my job because I can help people in need find what they need to be healthy and reach their goals. Being bilingual has given me the opportunity to help the members of my community that have communication barriers.

Tenal Alston

I have been at Duke for 5 years, serving as both a Nursing Assistant and an Advanced Health Unit Coordinator. After completing a Community Health Worker (CHW) certification course at DTCC, I began to better understand the importance of having outreach and resource persons within any given community. I enjoy providing helpful information to those who may not be aware of—or adequately informed of—those things that may help one make better health and lifestyle choices.

I have been in customer service for eight years. I feel good giving people the best version of myself and helping in whatever I can. I pride myself in being personable with rich qualities of loyalty and trustworthiness. I like being in a workplace where I will continue to help others and do something I absolutely love: using both of my languages!
