Insurance Specialist

Maria Hannawacker

I have 17 years of experience as a dental office administrator, patient care coordinator and insurance specialist. I joined the awesome Hills Family Dentistry team in 2014.

I love interacting and getting to know our patients. The opportunity to see our patient’s smiles transform throughout their treatment is so rewarding and fulfilling. I strive to provide the best customer service possible to ensure our patients have all their needs met.

I moved here from Seattle in 2013 and am enjoying this beautiful sunny state of California. I love the outdoors, exercising, playing tennis and going to the beach. I also enjoy playing the piano and cooking. I live in Carlsbad and have 2 grown and amazing children.





Born and raised in North San Diego County, I started my dental career in 2003 as a Registered Dental Assistant. I continued my education and became a Registered Dental Hygienist in 2009. My passion for a holistic, integrative approach has lead me to become an Orofacial Myologist and educating patients on how orofacial structures relate to airway health. I am passionate about the oral and systemic connection, keeping up to date with the latest research and comprehensive approach to overall wellness. Outside of the dental setting, I run my virtual Orofacial Myology practice, volunteer with animal rescues, hike with my dogs and spend time with my husband and family.


I was born in Denver Colorado (go Broncos!), grew up in Lompoc California, and moved to San Diego to pursue my dental career. After 4 years working as a Registered Dental Assistant with an emphasis in front office management, I went back to school, and achieved my Registered Dental Hygiene license in 2017. Since then, I have fostered a passion for the Dental Hygiene profession, and love educating the public on dental health. I strive to stay current with the most recent and accurate research to provide the highest standard of care for my patients’ health and wellbeing. I enjoy spending time with my husband, friends, and family. Also, staying active, snowboarding, and exploring San Diego’s beautiful beaches.
