Hygienist

Chriszelda, R.D.H.

A former bag lady-turned-Victoria’s Secret lingerie model-turned-cat-lady, Chriszelda decided on a career change later in life to focus on the healthcare field. Chriszelda received her degree in Dental Hygiene from the University of Texas in Houston in 2009. She developed a passion for cleaning very dirty teeth over the years and spreads that passion to her patients, encouraging them to brush and floss on a regular basis. Her passion has led to her reputation of spreading problem patients’ ashes by the railroad tracks behind the office.

On her free time, Chriszelda dotes on her grandchildren and loves to knit in her rocking chair with her cane by her side, swatting at the flies. On the occasion that there is a blue moon peering through the dark clouds, her inner cat-lady is unleashed and you can find her roaming the streets of Houston chasing after feral cats. She also tends to her chickens and garden on the weekends, growing cabbage, tomatoes, okra and watermelons.  She absolutely adores watermelon seeds.

*We will stick with this story until she turns in her bio. However, Chriszelda has actually been involved in the dental field since the 1900’s in various capacities, as an assistant, front desk, and meow as a Registered Dental Hygienist.
