Allery-Asthma-Anthony

Anthony Huynh, PA-C

I am from New Orleans, Louisiana and I graduated from the University of New Orleans in 2017 with a Bachelor’s is Biological Sciences. I spent the next 2 years working as a medical assistant at Urgent Care/Family Medicine. I graduated from the PA program at LSU Health Science Center at Shreveport in 2021. I wanted to become a PA because I was always seeing patients come who felt confused on their symptoms, conditions, and treatments. I wanted to learn more about medicine and be able to treat patients as well as help them have a better understanding of their health.

I wanted to pursue allergy, asthma, and immunology because I feel like these patients cannot fully enjoy their daily lives. Their symptoms will always be lingering around and it’s up to us to help them. Minor changes can cause major improvements.

On my free time, I like to exercise, cook, and write poetry.
