Kimberley Johnson

Office Manager / Registered Medical Assistant

I have worked at Desert Pediatrics since 2002 and in that time I have worked with Dr. Vondrak as his Medical Assistant as well as transitioning to front office and eventually office manager. I have enjoyed my time in this office. It is like my second home, and i enjoy my extended family.

I have learned so much from Dr. Vondrak and Dr. Nguyen and I truly enjoy all the families that come into our office. It is amazing to see the little ones grow into adults in front of your eyes. It always feels a little sad when they graduate to an adult doctor. I imagine it is like sending a child off to school or away from home for the first time.

Since I have been at Desert Pediatrics, I have had several life events. I was married in 2006 to my husband Peter and in 2008 we were blessed with our first daughter. Then six years later we were blessed again with our second daughter.

Anna Redondo

Front Office


My name is Anna. I am a native Tucsonan. I have been married for thirty years and have two beautiful and talented daughters who are eighteen and twenty-one years old.

I have worked for Desert Pediatrics in the front office for thirteen years and have always felt my years here have been quite a life-enriching experience.

One of the aspects of working in Pediatrics I most enjoy and appreciate, is the diversity of families we serve, from two parent families to single parent, grandparent caregivers, and wonderful foster parents.

I consider it a privilege to have the opportunity to work with each of our patient families in ensuring their children are receiving the best pediatric care available.

Virginia Sandoval

Front Office/Medical Records/Medical Assistant

Hello, my name is Virginia. I graduated from Pima Medical Institute in February of 2016 as an up and coming Medical Assistant. I started with Desert Pediatrics as a temporary Medical Assistant with Dr. Vondrak. Being that I was fresh out of school I never imagined myself working at a pediatrics office until i joined the team at Desert Pediatrics.

The Team was so welcoming and caring that I felt right at home since the very first day I started. I was saddened at the thought of leaving but was soon offered a full time position shortly before my end date. I was very excited at the though of getting to be around all of our fun-loving patients, I didn’t even give it a second thought.

Though I have lived in Tucson my whole life, I find that there is so much to explore about Tucson. I love exploring new book stores to find thrilling books that both my dog, Bailey Rose, and I can enjoy. One of my other favorite past times would have to be collecting Tsum Tsums which the kids really enjoy as well.

Stephanie Tinsley, RN.

Registered Nurse

I graduated from Pima Community College and started working as an RN at Banner Children’s hospital on the Pediatric Med/Surg floor, as well as the Pediatric Emergency Department.

I am a Tucson native and grew up on the east side of town. I have been married since 2012 and have 2 beautiful girls. I enjoy spending time with family, watching football, camping, 4 wheeling, and cooling off at the lake.


I started working at Desert Pediatrics in June, and I am looking forward to providing high quality, collaborative care for you and your children.

My name is Jesusita M. Cornidez but for short, everyone calls me Jes. I am a Medical Assistant and have been part of Desert Pediatrics for some time.

To tell you about myself, I am married to my wonderful husband. We have two little ones of our own and two puppies. They are a great support system and help me achieve all my goals. Life is great with them at my side.

At Desert Pediatrics, I work with Dr. Nguyen and when needed I work with Dr. Vondrak. We all help each other to give the best possible care to our patients. The best part about being here is seeing the children improve. When they come into our office, their smile can brighten anyone’s day!

I enjoy working with the people at Desert pediatrics an they have become my family away from home.
