So incompetent. Sadly, they only care about money and not their patients. It's lovely to receive a bill six months after the fact; conveniently after I stopped being a patient there. Also, if you have to miss an appointment even for an emergency they love to charge you $50. They are in the business of making money. The lack of customer service speaks volumes.

I LOVE everyone at Delta Bay Dental. They make me feel welcome and are interested in me as a person. They are professional and very qualified. Dr. Joseph is the best dentist I have ever had and Allie I love cleaning my teeth. When I moved to Walnut Creek 2 years ago I never even gave a thought to changing to a closer office! The extra drive is nothing in comparison to the quality of care I get and the quality of their "caring" about me. Now after a third year of driving I still choose Delta Dental as the best place to go for dental care! The drive is nothing compared to the 5 star Plus service!

I was so very thrilled with Tane and her entire staff. They were kind, gentle, happy and totally professional. I have gone to another dentist and would cry when they gave the shots. It was nothing like that there. They treat you with respect and caring. It's not just a patient, it feels more like they are treating their family. Both of my daughters have gone there as well and we are patients for life. We love Tane and all of her staff. Krista Mashore

The staff in the back that works for Dr. Joseph and Dr. Rontal are wonderful. Both Dr.s are amazing and very gentle. I hate going to the Dentist but if you have to go this is the place you want to go to. Allie the hygienist does a really good job and is super sweet. Would not hesitate to recommend the staff that works on your teeth and both Doctors. I have tried 2 other Dentists here in town and both ripped me off of a lot of money. So be careful in Brentwood whom you choose. These two are worth it.

My wife and I just switched dentists after moving out here 2 years ago. We didn't want to switch because we love our old office so much, but it became a hassle, so we decided to switch. It look about a month or so to get our first visit appointments scheduled, but it was worth the wait. Everyone was so amazing that we encountered. Everyone went into detail as to what they were doing and why and even talked us through a lot and showed pictures, it was great. We definitely enjoy this office so far!

I've been putting off a crown and filling for over a year! Due to a horrible experience at a previous dentist a couple years ago where I couldn't get numb. They Continued to give me shots over and over and over. Never explained side effects, like racing heart beat! And sweating! Just kept Giving me more shots until I told Them to stop And just complete the procedure while I endured the pain to Get it over with. Dr. Joseph was amazing!
I didn't get numb after the initial numbing shot I let her know. And she knew what to do! Got me numb! Explained it all to me! And made it an experience of no pain! highly recommend her! We are moving out of state in the next few months. And I will definitely be flying back here for my dentist needs!

Dr. Rontel and her delightful crew have been caring for my smile going on 3 years now. Always professional with that friendly warmth that you enjoy from caring, thoughtful people. all the qualities you look for and expect from everyone but find so little of in today's world. Theses days you always feel rushed or "just a number", but here we feel welcomed and invited.
I even enjoy the local photos on the walls. just those kind of little details that gives me confidence that the people around me are grounded to the local scene and are interested in the community. it's also fun seeing Dr. Rontel's smile showing up in 110 degree magazine, then in the grocery store carts then sponsoring a hole at a local golf tourney. makes me feel connected to a local success story who invests into the local economy. it just reinforces my belief that they care about me inside and outside the office: They have convenience of text reminders too that have come on handy too! Accommodating, caring, professional.can't say enough about Dr. "Tane" Rontel and her crew!

This is the best dental office I have been to. I was scared to find out what my exam showed. Everything was explained so well by Dr. Rontal. The staff is very nice and the office very clean. I have been hopping from dentist to dentist but I don't have to anymore. When I went back for my fillings I didn't feel any pain and now that I'm not numb anymore it feels like nothing happened. I definitely recommend Dr. Rontal for all your dental work!

Poor customer service, rude office staff and in general a gang of money grubbers. They specialize in setting appointments far in the future, and then hit you with a $50 missed appointment fee. I asked them on numerous occasions to notify me of appointments, but they never call. They also tried to convince me to have my old reliable silver fillings removed and replaced with ceramic, which is a scam I had already wised up to after finding out the hard way that the white ceramic replacements almost invariably lead to broken teeth.
