Pediatric Dentist

Dr. Joshua Westphal

Dr. J.D. Westphal is passionate about pediatric dentistry. Though he was scared of dental visits as a child, the more he learned about dentistry, the more interested he became. Today, he channels those early childhood experiences to help his young patients feel more comfortable. When asked what’s the best part of his job, Dr. Westphal replied, “There is no better feeling than helping a child overcome their fear of having a procedure done in the dental chair.”

Dr. Westphal earned his dental degree at The University of Nevada, Las Vegas. He then completed his post-doctoral specialty training in pediatric dentistry at Virginia Commonwealth University. There, Dr. Westphal became skilled in pediatric medicine, sedation, anesthesia, and behavior management. He is also Board Certified.

Dr. Westphal is thrilled to be living on Oahu with his wife Ashley and three boys. He enjoys spending time outdoors and loves mountain biking and hiking. In addition to balancing a full family and professional life, Dr. Westphal makes time to give back to the community. His Spanish-speaking skills helped him provide care during several dental mission trips to Mexico and Honduras. He remains active as a dental volunteer for Mission of Mercy, Give Kids a Smile Day, and the Veterans of War dental clinic.

The wait to get in for an appointment was quite lengthy but everything was great when we finally got seen. My 10 month old had his first dental appointment with Dr. Joshua Westphal and it could not have gone better. Dr. Westphal was patient, caring and made everything super simple.

I like an appointment that is on time. The bonus was that Dr. Westphal and the hygienist were both very nice and professional. Quality and excellent service.

I always grade objectively from beginning to end: Making an appointment: Call was answered timely, great customer service on the phone, easy to make an appointment, and a reminder communication sent to me. Kudos! The only obstacle is that they are VERY popular (and for good reason), so you must wait for appointments. Appointment day: Easy to find. I walked in and ALL staff greeted me and my kids. At the first appointment and each subsequent appointment, I was given forms and the wait to get started was under 10 minutes. Location: The office is in a shopping block in Miliani but not hard to access or find. The office itself is on the second floor of the building, but there is an elevator to help those who can't do stairs access it. Office is always very clean, comfortable, and appropriately air-conditioned. Parking: The parking is beside the building. However, it does share parking with businesses in the same building and will fill up during peak operating hours. So you want to make sure you're early enough to find a space and get to the appointment. No fees to park. Dental exams: Everyone who worked with my kids was truly VERY friendly. They seemed knowledgeable, efficient, and competent about what they were doing. My kids saw Dr. Westphal who is AMAZING! 10/10! Equipment: They have up-to-date equipment and services. Even though you think the office is small, they do a whole battery of expected services there. You can tell they invested resources into the practice. Customer Service: From beginning to end, everyone was VERY nice. You can tell that the staff has a great relationship with the doctor (Westphal). We had to do a few different practices when we moved to find a place that checks all the boxes, but I think this office was a very lucky first find!

The office was welcoming and professional from the moment we walked in the doors. My son could not wait for his scheduled appointment due to a toothache so the office squeezed us in the next day. The assistant settled us in, and Dr. JD Westphal came in and reassured me and my son that the tooth that is bothering him will be taken cared of. Dr. Westphal and his assistant did a great job with my son. They kept communicating to each other and to my son. The front office discussed the finances and explained each charge. Thank you Hawaii Family Dental Ka Makana Alii 🤙🏼🤙🏼 We hope to keep the visits to a minimum to the twice a year cleanings 🤞🏼😬

My daughter went in twice in 2 weeks to have work done on both sides of her mouth. She is not a fan of the doctors or dentist. But I must say she came out the first time better than I could’ve imagined. The second time was a bit harder. But overall she had the best experience that a mom could’ve wanted for their child. The work is all done and she is just a happier child. Thank you to doctor Westphal and the staff at Mililani Hawaii Family Dental Center for the care and services you provide!

Everything about this location is AMAZING! I love the staff & the doctors! Even transferred my daughter here, best decision ever! The wait is never long. Cleanliness is on point! Always friendly! They are just fantastic! I’ve been going here for about 8 years. My daughter started seeing Dr. Westphal, I can’t tell you how wonderful he is! They do not strap children down which was my daughter’s first procedure without being strapped down (since her previous pediatric dentist always did it) & she did great here! With the help of Dr. Westphal being quick & agile. He also comforted her the entire time. I really appreciated that he gave me ALL the options to choose from rather than telling me what he has to do. Highly recommend! Nani is my hygienist & she’s gentle & is the sweetest! I now see Dr. Hall & he is also great, I had recently switched to him because my Dr was not in during my visit & I enjoyed him so well that I asked to be switched. Lol! Dr. Tom was my ortho for 7 years till he retired & I now see Dr. Shin. He is very thorough, I’ve had my permanent retainers on for a while with no problems. Lastly to Skye, Quadra & to the other women, thank you for always making my visit so pleasant 🙂 See you all soon! -Berna
