Have questions? We’re here to help!
At Castle Pediatric Dentistry, you can be confident in the dental office you have chosen for your child. From your first visit, we want you to feel welcomed and well cared for.
Dr. Keren Castellucci and her team promote preventative dental care including a healthy diet and great oral hygiene at every visit. Because of this, we love to have parents present during their children’s dental appointments. This gives us the opportunity to educate you as well, so you can help reinforce these healthy habits at home.
We at Castle Pediatric Dentistry are focused and committed to providing optimal dental care in a friendly, caring, and family-oriented atmosphere. Our Mission is to provide the highest quality pediatric dental services with an unsurpassed commitment to the dental wellness of our patients and to also educate our patients, parents, and community in preventative dental health care and in “Healthy Ways of Living.” We strive to provide superior service to our patients as well as parents and guardians. By establishing and nurturing relationships with our patients and their parents, we make it our goal to diagnose, prevent and educate children and their parents about best practices for superior dental and oral hygiene.
Keren Castellucci is the owner and founder of Castle Pediatric Dentistry. Opening the practice in 2022, she was thrilled to bring her years of experience to Winter Springs and the surrounding communities. As she shares, “It has been a lifelong dream of mine to be a Pediatric Dentist in the community where I grew up and where I am raising my family.”
Being raised locally, Dr. Castellucci was proud to attend the University of Central Florida, earning a Bachelor of Science in Molecular and Microbiology. Go, Knights! She completed her Doctorate of Dental Medicine at Nova Southeastern University in Ft. Lauderdale, FL. Dr. Castellucci’s passion for pediatric dentistry radiated in her commitment to education and giving back to the community throughout dental school. Upon graduation, she received the American Academy of Pediatric Dentistry Certificate of Merit Award.
After completing dental school, Dr. Castellucci attended a two-year pediatric dentistry residency at Nova Southeastern University and Joe DiMaggio Children’s Hospital. She served there as Chief Resident during her second year. During her residency, she focused her training on providing comprehensive care for pediatric patients, including those with special health care needs. Immediately after completing residency, Dr. Castellucci returned to her hometown to provide pediatric dental care to the children in Central Florida.
Dr. Castellucci is board-certified by the American Board of Pediatric Dentistry. She has been an advocate for the profession throughout her career and served as the 2019-2020 President of the Florida Academy of Pediatric Dentistry.
“Working with children reminds me of how magical the world can be and encourages me to ignite my imagination and find creative ways to relate to children of all ages.”
Dr. Castellucci has an enthusiastic attitude towards providing dental education and care to her patients and their families. She prides herself in making each visit a comfortable experience, creating a relationship where her patients enjoy going to the dentist. Dr. Castellucci feels truly blessed to have the opportunity to make a difference in the lives of children daily.
Dr. Castellucci married her high school sweetheart Jonathan. They have two beautiful daughters and a standard poodle. You might even see Winnie-the-Poodle at the office working alongside Dr. Castellucci and the Castle Pediatric Dentistry Team!
