Donald De Berry, DDS

Um don’t go here. Save yourself the time and don’t schedule an appointment.
Yes, this «dentist» is in a creepy little house, no one else is there, not even ANYONE to help him. He has his private home upstairs. And the equipment is ancient and deafening. I literally thought i was going to lose my hearing or something with the high frequency of the drills. He did not do anything to help my teeth except poke a metal needle around. it smells so gross in there *shivers* this is weird. and i’m not sure how it still is running…

Wow, all these negative reviews just because the man runs his dentistry out of his house. So what? I’ve been going to Dr. DeBerry for the last 8 years, and he’s always taken his time and done a good job with my teeth. Sure, it’s unorthodox to walk into someone’s home to get your teeth worked on. And yes, Dr. DeBerry has a life outside dentistry that is unorthodox. If that «creeps you out», then stick with your antiseptic, professional office buildings, or better yet, find a dentist in Walnut Creek, not downtown Berkeley if appearances, not professional experience, is your main concern.
Dr. DeBerry is friendly, professional, and has a steady hand. He’s been at it for many years. He has all the right tools, and you never have to wait in some room for half an hour, ignored, with cold, impersonal assistants handling you. I will continue to see Dr. DeBerry until he retires.

Yeah, this totally freaked me out and was extremely uncomfortable. I have very sensitive, cavity-​prone teeth, and he was less than careful when cleaning my teeth. He didn’t even check for cavities how all my other dentists have, e.g. poking the surfaces of the molars to check for decay. So now I almost feel like I need to go to a different dentist just to make sure nothing’s wrong with my teeth. And ditto about the house thing. That place cannot be sanitary.
On another note, he left in the middle of the cleaning to «turn on the lights,» which I think meant that he went into the basement or something to switch on the generator or fusebox. So weird.
I’m sure he knows what he’s doing since he’s been at it for like 50 years, but it still creeped me out. Never again will I go to this dentist. Avoid this place if you have the standard UC plan! I’m sure every other dentist in the area is better than this guy.

Holy moly.
Picture this…
You go to the dentist. The address takes you to a run down house with no sign. When you peer in, it looks like a hoarder is living there and there’s an 8.5 by 11piece of colored paper with «Dr. De Berry» written in black sharpie on the inside of the door (taped on one of the boxes).
You call Guardian and say (basically), «This is absurd. What the hell do I do?»
Then you go to door, meet Dr. De Berry, and tell him you don’t feel comfortable having an appointment with him.
«Oh-​right. Because I run my business out of my house.»
«Uh… Yes… That’s right Dr. De Berry…»
