Irene Blaess, DDS

Dr. Blaess grew up in Houston since the age of eight, graduating from Sharpstown High School. Upon graduation, she attended the University of Texas in Austin, receiving her dental degree in 1997 from the University of Texas Health Science Center. After spending a year as an associate dentist she established her first practice De Zavala Dental, in November of 1999. After hiring Dr. Zebrowski in 2002 they partnered to open Northwoods Dental Spa, the first dental spa in San Antonio.

Continuing education plays an essential part in Dr. Blaess' office. With constant improvements in equipment, materials, and techniques, she believes it is vitally important to commit time to keep learning. Dr. Blaess and her staff attend many hours of continuing education courses every year, far beyond the necessary amount required to maintain licensure. They include lectures, hands-on courses, and practice management programs. Staff members also learn from each other and from their patients on a daily basis.

Dr. Blaess supports organized dentistry and the way organizations promote the health of our citizens. She is a member of the San Antonio District Dental Society, Texas Dental Society, American Dental Society, and Academy of General Dentistry.

On a personal note Dr. Blaess is a wife and mom of two great boys, Michael and Brian. She loves to travel, dance, and entertain with husband Michael, family, and friends.
