Dr. Sebastian Nuñez

Dr. Sebastian Nuñez was born and raised in Cordoba, Argentina. He grew up in a large family who many had their own business.

The Dr. quickly realized he loved being surrounded by people, as well as, serving his small community. Sebastian received his dental degree at the University of Cordoba in 2005. Dr. Nuñez moved on to pursue and earn his Doctorate of Dental Surgery from the University of Michigan in 2009.

It was in that same year that he moved to the Lone Star State! The Dr. had been an associate in the Texas City area until 4 years ago now starting his own practice. He is now happily serving the Baytown and surrounding communities. He is doing what he loves the most and taking care of your dental needs to provide the best care possible.

Dr. Nuñez has been a member of the AGD since 2011. Continuing education plays a big part in Dr. Nuñez’s practice. It allows him to stay up to date with new materials, advancing his research, and improving his skills.

When not attending to the care of his patients, you will more than likely find Dr. Nuñez at home with family and friends or out fishing!
