Dr. Joseph Renzi, Jr


Welcome to Orange County Pediatric Dental Group!

Dr. Karilyn House, Dr. Joseph Renzi, and their highly-trained staff recognize that many patients have needs as unique as their smiles. Children tend to become extremely anxious when in the dental setting especially in children with emotional, mental, sensory, physical, or other developmental delays. 

At Orange County Pediatric Dental Group, we’re passionate about kids. Our entire team works hard to help your child learn about the importance of their oral hygiene, which helps them become happy, more confident dental patients now and in the future.

As your leading team of pediatric dental specialists, we want to ensure your child knows there’s nothing to fear when visiting us for treatment as we hold ourselves to the highest level of standards when administering dental care.

Help your child achieve life-long oral health and a beautiful smile that lasts by calling us today to schedule their dental appointment! We look forward to meeting your family!

Providing a Wide Variety of Pediatric Dentistry Solutions

Much of the care we provide is preventive and educational, that’s only outmatched by our compassion for helping children.  We truly enjoy helping young ones and their families understand the best ways to practice oral hygiene while keeping oral health issues at bay.

We offer a variety of dental services that are always personalized to meet the needs of your child. They include, but are not limited to:

Along with providing a completely individualized approach to your child’s dental care, our office is designed to help children feel as comfortable and welcomed as possible.

From cheerful office décor to specialized instruments that comfortably fit within developing smiles, we aim to make every child’s experience with us a positive one.

Specialized Dental Care for Your Child

Our Santa Ana team happily treats children of all ages and those diagnosed with certain syndromes and chromosomal abnormalities, such as cleft lip or palate.  We also see a large number of patients who span the range of the autism spectrum (ASD).  Often, our patients with special needs have complex medical conditions and take multiple medications that require consideration when planning for treatment.

Children with special needs require regular care to maintain their oral health.  We find that routine visits help desensitize patients and that over time, patients become more comfortable with each visit. Patients with special needs can benefit from visiting a pediatric dentist who is uniquely qualified and trained.

Both Dr. House and Dr. Renzi are Pediatric Dentists.  This means that they have received the extensive training necessary for managing the oral and dental healthcare of children and people with special needs.  Our doctors also coordinate with other medical specialists to ensure children of every spectrum receive the quality of care they deserve.  

As Dr. Renzi and Dr. House are long-term members of Medical Staff at multiple hospitals in Orange County, we can provide care in the hospital operating room and outpatient surgical center when needed.  

Orange County Pediatric Dental Group is proud to offer dental care in these settings as a very limited number of Pediatric Dentists provide dental care in hospital and surgical centers.
