Meet The Staff

Our Team

Sandy Saenz


I'm  Sandy Saenz and I have been a hygienist now for almost 31 years, graduating from the Dental Hygiene program at FCC in 1986. Out of those 31 years I have spent 30 of them working at this dental you can see this has been a great place to work. I am married to a wonderful man named Pablo, who is a school teacher in Orange Cove. I am also a mother to two grown sons who are my pride and joy. One lives in San Francisco and the other lives here. Some of my interests include music, outdoor activities, and taking on projects at home. 

Shana Freed


I am married with four children.  I spend half my time in the valley and the other half in the San Francisco Bay Area.  My family is very important to me and I love hiking, camping, and going to the beach with the my whole family.  When not being active we also enjoy cooking and spending quality time together. I began my career in dentistry as a dental assistant for a periodontist here in Fresno.  After being a dental assistant I moved on to complete my education to be a dental hygienist and I am now happily helping patients to improve their oral health through improved hygiene. I have been with Dr. Jack since I got my RDH and I enjoy working with this unique and wonderful team.  

Rosana Alvarez

RDA / Appointment & Treatment Coordinator

Hi.  My name is Rosana.  I am a registered dental assistant and have been assisting for twenty one years.  For nineteen years I have worked with this office and we are now more family than co-workers.  Dr. Jack joined our work family more than ten years ago and we have had a great time working together.  I love getting to know my patients and making them part of our family as well.  

Family is very important to me and in November of 2017 I will be getting married.  Planning the wedding has kept me very busy outside of work.  Besides wedding planning I am always very busy playing with my two fur babies, and watching my niece and nephew and God kids at all of their extra curricular activities.  I am a huge sports fan so I can usually be found watching one of the kids playing on the weekends.  


Mireya Tovar


Hi, I am Mireya Tovar. I began the dental assisting program at Reedley College in 2002 and received my registered dental assistant license in 2004.  During my externship with Dr. Downing's office I was hired on and worked for him until he retired in 2014.  I became Dr. Jack's assistant in 2006 when she came on as Dr. Downing's associate, and have remained with her since her acquisition of the practice.  Working with someone for so long makes it feel like working with family.  

I am an overjoyed mother of four, Steven, Stephanie, Presley, and Royce.  They are my world and they keep me busy and out of trouble.
