Hi everyone, I’m Dora!
After completing dental school in 2020 and working as a dentist in Poland for a few years. I decided to pursue my career abroad.
Drawn by the warm climate and vibrant culture of Arizona I made the bold decision to relocate to Phoenix. I embraced the opportunity to join The Kids Dental Office of Phoenix and Orthodontics as a dental assistant.
Outside of dentistry I enjoy exploring Arizona’s natural beauty, from hiking trails in Sedona to the picturesque landscapes of the Grand Canyon. I am fluent in Polish, Russian, Turkish, Tajik and English, allowing me to connect effortlessly with people from various backgrounds and ensure they receive personalized care.
I look forward to continuing my journey in pediatric dental care in Phoenix, where every day brings new opportunities to learn, grow, and positively impact the oral health and well-being of our community.
