She is a Louisiana native,  but has called Oklahoma home for the last thirteen years.  Family is everything to Mindi, and when she isn’t caring for patients, she is spending every minute with her husband and three beautiful sons. Her family keeps her busy with lacrosse games, basketball games, school dances, and everything that comes with raising three boys. When she isn’t with her boys she can be found in her craft room creating a new project.

She then continued to build on her foundation by attending Northwestern State University (Louisiana), and South University, Georgia.  She is truly a southern woman at heart! Mindi has obtained triple masters Nurse Practitioner degrees in Women’s Health, Adult, and Gerontology, and is board certified through the American Association of Nurse Practitioners (AANP). Mindi’s passion for adult & geriatric health really shines throughout our practice.

To support this approach, she has gained knowledge that specializes her in weight loss, obstetrics/gynecology, public health, geriatric care as well as aesthetic medicine.
