Your Precision Smiles Team (from left to right):Anna, Susanna, Laura, Dr. Shai Patel, Joy, Ashlee, Cristina



Laura Williams, RDH

Laura became a Registered Dental Hygienist because she wanted to be able to help individuals become and stay healthy. She graduated from the Dental Hygiene program at Midwestern State University in May 2005. This is the same time that she met and fell in love with her wonderful husband Ricky. She has been practicing dental hygiene for over 10 years now, and she loves to build personal relationships with her patients. She wants not only to educate her patients about oral hygiene, but also wants to take the fear out of dentistry. She has been with Dr. Patel since 2009 and works closely with him to provide patients with optimum oral health.

When she is not cleaning teeth, she enjoys spending time with her 2 handsome boys, Kaden and Ethan, and her fun loving husband. She also likes to read, CrossFit, and has recently taken up running. She loves to watch the Green Bay Packers! Go Pack Go!!



Cristina Fersiva, RDH

Cristina has been a dental hygienist for over 15 years. She graduated from Howard University in Dental Hygiene. She loves educating her patients on their oral health and helping them obtain a healthy smile!

Cristina has been happily married to her husband and has one beautiful daughter. In her spare time Cristina enjoys spending time with her family, baking, traveling and volunteering. Cristina and her family moved from Virginia over 5 years ago and they love Texas.



Anna Barret, Lead RDA

Anna is our Lead Dental Assistant and has been with Dr. Patel since he opened his practice in 2009. She was born and raised in South California and moved to Texas in 2005. She became an RDA (registered dental assistant) in 1992. Anna specializes in caring for patients from pediatrics to geriatrics. She has a big passion for dentistry and her patients.

Anna has two beautiful older children and her grandson, Zayne, that makes her glow on a daily basis. Anna said she has really enjoyed getting to know our community and thinks of our patients as family. She is Dr. Patel's right-hand man and he would be lost without her!


Christina Cagle, RDA

Christina (AKA Tina) became Dr. Patel's 2nd assistant in January, when she won us over with her team player attitude. She loves connecting with patients and making them feel comfortable. Her love for dentistry started young, when she would ask lots of questions at her dental visits! She has been a dental assistant for 4 years and truly loves it.

She has been married to her husband, Brandon, for 3 years, and they have a 2yo son, Austin, who is their pride & joy. They live in Princeton, where Tina grew up, and she is actively involved in her church in Allen. She enjoys being outside, country dancing, and crafting with her sister.



Ashlee Dilloway, Office Manager

Ashlee is our new office manager & billing/insurance specialist. She joined the Precision Smiles team in the summer of 2016 and has fit right in with the team! She started as a dental assistant back in 2004 and quickly realized her passion was at the front desk, where she worked at the same office for 12yrs before coming here. She has extensive knowledge, working with billing and dental insurance claims. She is here to ensure that your insurance claims are paid correctly and understands that nobody likes to be surprised with an unexpected bill from your dentist. As a detail-oriented perfectionist, she will maintain accuracy with your account and make sure that you are happy with your experience at Precision Smiles. She also works directly with Dr. Patel to prioritize your dental needs, and she truly enjoys helping patients be able to afford their dental treatment.

Ashlee lives in Little Elm, with her husband, James, and their 2 daughters, London & Brooklyn. In her spare time, she enjoys baking cupcakes (and boy, are they good!) and watching her girls play soccer. She's also a huge Dallas Cowboys fan and loves watching football, and her favorite place to be is at the gym, lifting weights!


Joy Rodgers, Insurance Coordinator

Joy has been with our team since September 2016 and we know you will love her as much as we do! Her name fits her personality--she is the happiest & bubbliest member of our team (probably ever) and you can't help but be happy when she's around. Joy verifies all our patients' insurance before you come in for your appointment, to ensure we have all the information we need about your dental benefits. She has worked in the dental field for over 12 years and LOVES talking to patients and getting to know them!

Joy lives in Frisco, with her husband, Brian, and their 5 kids. She loves spending time with her family, traveling with her husband, and cooking everything! She is a super proud mom and enjoys going to cheer on her kids at all their extracurricular activities. She also loves running and yoga.


Kaila Martin, Patient Coordinator

Kaila is brand new to the office and boy, is she a breath of fresh air! We knew right away that she would be a great fit. She's the first voice you'll hear when you call and the first pretty face you'll see when you come in. She is our new patient coordinator and will help you with all your scheduling needs. She has worked in dentistry for 4 years, but with her expertise, it feels like 14 sometimes.

A Dallas native, she lived in Austin for a short time, but realized her heart belongs here. Being a true Texas girl, Kaila of course enjoys country music & dancing! In her free time, she likes to spend time with her friends and her adorable Godson, Landon. She enjoys being on the water and being outdoors!
