Hello! My name is Jennifer and I go by Jenny. I am so happy to be a part of the Advanced Dental Care of Austin’s team. I have been a Dental Assistant in Austin and the surrounding areas since the ’80s. I got into the dental field when I was eighteen years old. I loved it then and I still do. My main goal is to make my patients comfortable and well cared for during their dental experience. I am especially skilled in working with those who are a little nervous about dentists and dental work. Over the years I have had a lot of experience in cosmetic dentistry and I love my part in creating beautiful smiles.

Hi! My name is Betsey. I joined the team of registered dental hygienists here at Advanced Dental Care of Austin recently, when the practice I had worked in for 20+ years merged with Dr. D’Abadie’s practice. I have enjoyed working in the dental field for over 30 years now. While growing up in Abilene, I started working part-time for my childhood dentist right after high school. This ultimately led me to dental hygiene school. I graduated from UTHSC-San Antonio and became a hygienist in 1988. After moving to Lubbock for a few years, I landed in the Austin area and have been here since 1992. I have two great kids that I love spending time with. My son is a student at Texas Tech and my daughter is a student at RRHS. I find being a dental hygienist to be very rewarding when I know I have made a difference in helping someone achieve dental health and have a positive dental experience. I look forward to meeting you and working together so we can meet your dental needs.

We had the pleasure of partnering with amazing organizations recently. We were made aware of the opportunity while working with CADF (Capital Area Dental Foundation - the philanthropic arm of the local dental society) Season for Caring. In partnership with AAS (Austin American Statesman) and HAAM (Health Alliance for Austin Musicians), we were able to help care for a family. HAAM provides access to affordable healthcare for Greater Austin’s low-income, working musicians, with a focus on prevention and wellness. HAAM has helped 6,500 musicians across seven counties access over $123 million in healthcare services since we began in 2005. Services include routine dental work, doctor visits and prescriptions, psychiatric counseling sessions, eye exams, outpatient procedures, specialist referrals, hearing screenings, basic needs assistance, and more.
