Karla Finger


Having started my dental hygiene career at the age of 20, I have had a very diversified journey throughout the years. I have worked in just about every setting that is available in dentistry, including all institutions and specialty clinics. I have always been interested in the periodontal aspect of dentistry and have therefore worked in that capacity as often as possible. My desire to be engaged with periodontal patients therefore lead me to work here at South Texas Periodontal Associates 16 years ago.

I enjoy my patients here, while teaching them the many ways of achieving optimum periodontal and overall oral health. I am also fond of my South Texas Periodontal Associates Family.

I am currently transitioning to “City Life” from rural living and finding I am enjoying the many amenities available to me.
