One of the most fascinating rewards from working in the medical field is the fulfillment I get from helping people reach their highest state of health and wellness. After working in numerous ancillary healthcare positions as an undergraduate from 1990 to 2011, I finally attained a Master’s degree in Nursing from University of Texas – Pan American in 2012. A lifelong commitment to education led me to attain Board Certification as a Diabetes Educator as well. Such education and credentials ensure high quality care for individual patients, their families, and diverse populations. I really enjoy and feel a great sense of responsibility to provide upmost care for those I serve at the clinic.
