About Us

Credentialing with the government and health insurance companies continues to be a complex and time-consuming management function for practices of all sizes. Few individuals truly realize how labor-intensive it can be to fully complete the credentialing process. Our team of extremely knowledgeable, customer-driven professionals work to make the credentialing and contract management process as painless as possible. At Nationwide Credentialing, we work with you from start to finish on the credentialing process, which allows physicians and their staff to focus on patients and other important aspects of their practice.

CEO & Managing Partner, Tammy Luker

CEO & Managing Partner, Tammy Luker

Tammy started with this company as Manager of Operations “way back” in April 2000 and was instrumental in the startup and development of the company then under another name and ownership.  Tammy was solely responsible for the development of the current website as well as handling all sales for the company.  In 2006, Tammy was promoted for her efforts to the position of CEO.  She continues to hold that title but now has realized one of her goals to become a business owner.  She and her business partners were able to purchase and acquire the company in August of 2011 and changed the name to Nationwide Credentialing.  Tammy has always had the attitude that Customer Service is of the greatest importance and has instilled that quality in the people who work for Nationwide today.  Most of you know her today as the “energetic voice” on the phone with the big laugh! Tammy says, “I am so excited to be able to do the things now that I’ve always wanted to do with this company but never had the resources.  It means a lot to me to be able to visit our clients face to face and really get to know them and get their feedback.  I look forward to continuing to help our clients, because that’s my favorite part of my job!”
