Yazmin Fabela – Lead Veterinary technician

Yazmin Fabela – Veterinary technician 

My goal in this field is to help as many pets as possible. Getting to know the patients is the highest priority so I can than help the Dr. with any treatment they need. 

My most recent and impressive achievement I have done is doing dentals. I can get a dental done with x-rays within 30-45min. 

A fact about me is I always wanted to work in this field because I wanted to help those who don’t have a voice.
