Dana developed a passion for dentistry at an early age from working at her father’s dental practice in Michigan. After moving to Chicago post-college, Dana began her 12 year career managing dental offices. Recently Dana moved from Chicago and is so happy to have her family be a part of the wonderful Barrington community.

Dana’s goal is to make excellent oral health attainable for everyone. She says, “It’s important to me to get the message out to patients about how much your oral health affects your life; from preventing serious diseases to your relationships to your self-confidence.” Dana’s degree is in Organizational Psychology, so she strives to create systems and protocols that give patients the best care possible. “When I recommend patients to an office I have to absolutely believe they are in the right place, and that is why I am so happy to join the team at Barrington Smiles. Not only is Dr. Saad extremely talented in all aspects of dentistry, but he takes special care of each patient to ensure they are well-informed about their treatment. Donna is one of the most knowledgeable hygienists I have ever worked with, and Natalie and Laura go above and beyond to check every detail of appointments to ensure everything goes smoothly.”

Dana's family keeps her pretty busy, but when she does have free time she enjoys reading, biking and travelling. 

Laura Soto is our insurance coordinator. You will find her at the front desk working diligently to maximize our patient’s insurance benefits. Laura’s 5 year tenure has also given her opportunity to assist chair side. That chair side experience has provided a better understanding of the nuances of treatment procedures, which enables her to be more effective as an insurance coordinator.  Laura says, “I find it very rewarding to help our patients in any way I can.'

In Laura’s free time, Laura loves to draw and color. Her favorite “super hero” is Batman, because he doesn’t need any special power to be a hero. Laura looks forward to meeting each of you!

Natalie Perez joined our team as a dental assistant in 2020. Her desire is to be in a field where she can help people. Natalie is cross-trained and you may even see her in a front desk role on occasion. Her love for dentistry has inspired her to want to continue her education in this field.

Natalie has two children and enjoys spending time with family. In her spare time you will find her cooking and baking. Natalie looks forward to working with each patient to help them attain their dental goals.
