For nearly 13 years Jay has been working at our office! Yah baby! Jay actually worked with Dr Dumitru over 20 years ago when they were both still young bucks. Jay is experienced in all aspects of Dentistry. He grew up in California in the Newport/Huntington beach area and was always the popular guy, just like here at work. Jay is still a die hard Lakers fan despite the last several years of disappointment. He only cries on the inside when the lakers lose to the clippers. He is still a legit O.C. guy. Do you need to know the latest style in hair or clothes? Check Jay out! He wears scrubs here at work, but outside of work he has the most style of all the employees. Sorry female employees:( Jay has 2 grown boys that are black belts just like him. He also has one beautiful daughter.

A lucky lightning bolt hit our office when she started working here. She was a retail store manager on the east coast and was recruited to run another business here in mesquite. Fortunately, with a busy family, she decided to put time into her wild boys and gives some of her time to us! Julie husband is from New Zealand and was recruited to come to the states to play rugby. They have 2 girls and now 1 young stud “Iz” together. Her kids are growing real fast, but for now Julie can still take them all down. Call her and you will get the “perfect” phone voice! She will record your personal phone message on your home answering machine…for a small fee:)
