Celina Tellez

Medical Assistant

Hello! My name is Celina. I was born and raised in Mesa, AZ. I have one son who is such a joy in my life. Outside of work I like to spend most of my time with my family and friends. I love to travel and love to attend any concert I can. I have been a medical assistant since 2011 and have been working side by side with Wendy since December of 2012. I have worked in a couple other offices throughout the years, but have been in pain management for the majority of my career. Our patients here are like our second family. I love being apart of OnCall Pain and I love what I do.
