This family history explains why he feels such a special bond with the people of this area,

Dr. Drgac is most excited about providing quality care to his patients here in Burleson County. He says, “There’s no need to drive to a larger city for dentistry anymore. Besides, who’s going to take better care of you? A person you see 2-3 times a year, or someone you see all the time around town, in church, etc.?”

Family is very important to Dr. Drgac. He loves to spend his free time with his wife, Nicki, and their three children: Dylan, Daleigh, and Delayni. Nicki is a hometown girl, graduating from Caldwell High School in 1991 and Texas A&M, class of 1995. They are so thankful to raise their family in this wonderful community!
