Kim Hoang, DDS, MSD
Board Certified Pediatric Dentist

Nurturing a long-term relationship with my patients is a top priority. I believe that providing gentle and conservative care for my patients is one of the most important components to create a positive experience for both the child and their parent(s). One of my main goals is to make the visit to our office comfortable and interactive, so that the children leave looking forward to their next visit because of what they learned and how much fun they had!


I originally grew up near Portland, Oregon where I came to appreciate all the unique offerings of living in Portlandia.  Later, I moved up the coast to Seattle to attend the University of Washington for college. I remained on the west coast to earn my Doctor of Dental Surgery degree at the University of California, San Francisco. At UCSF, I graduated with several top honors and recognition for remarkable community service. I would often seek out extra treatment opportunities at community clinics, to provide infant oral  exams and teach  dental education to

underserved families. This is where I discovered my passion to treat children exclusively and decided to pursue advanced training to specialize in pediatric dentistry. I received my Master of Science degree in Dentistry at the University of Texas Health Sciences Center in Houston.  I am a board certified pediatric dentist who is experienced in conscious sedation, IV sedation, and hospital dentistry. I have been practicing pediatric dentistry in Texas since 2008 and have settled in Austin to be close to my family.


Aside from work, I have recently become an avid participant in sprint triathlons.  I’m proud to say that I’ve completed three triathlons during my inaugural year (2013) in the sport and I plan to continue training and competing with my siblings and cousins in future triathlons.  I also enjoy ultimate frisbee, snowboarding, tennis, paddle boarding, cooking, and traveling.

Noel Sint, DDS, MS
Board Certified Orthodontist

Born and raised in Southern California, I stayed close to my family and attended the University of California, Los Angeles (UCLA) for college. Like many others, I was a young adult in college who felt some insecurities about my appearance. It didn't help that I was also a freshman in college with braces on. I didn't truly realize how much my crooked teeth could affect my social interactions with other people, until the day my orthodontist took my brackets & wires off. That's when my smile was finally straight and I started noticing a huge change from within. Almost instantly I was beaming with more self-confidence and joy. This change helped shape my personality into who I am today.  My braces changed my life and were the driving force towards my decision to apply for dental school; I wanted to help people find a similar positive change in themselves. That's when I knew I wanted to become an Orthodontist.


Although I had the aspirations of becoming an orthodontist early in dental school, during my junior year I decided to use my skill set to support

a greater purpose and take part in a different way of life. I accepted a commission to become a Captain in the United States Air Force and served as a general dentist for three years. I viewed being an officer and a general dentist in the US Air Force as an opportunity to grow and improve both as an individual and as a clinician while contributing to a larger cause. I welcomed the unique opportunity of living overseas and was fortunate to be stationed near Cambridge in the United Kingdom for two years. After completing my service with the Air Force, I moved back across the pond to New York City to obtain my Orthodontic Specilization at Columbia University, College of Dental Medicine.


After completing my Orthodontic specialty training in New York, I moved to Austin, TX to practice orthodontics and to finally live in the same city as my wife.

​I was born in the great city of Austin, TX and raised just a stone's throw away in Buda. After graduating high school, I decided to make Austin my forever home. In my spare time, you can find me floating the river with my dog Benny, walking along Town Lake, or spending hours in front of the TV binge watching my favorite Netflix series. Dentistry has always sparked my interest, and in 2015 I received my registered dental assisting license. I greatly enjoy spending my day with kids and working at Petite Dental & Orthodontics has successfully allowed me to do that.
