My dental team practices state-of-the-art dentistry. While we guarantee a professional and courteous team, my staff prides itself on the way each patient is personally accommodated, from the moment they walk into the waiting room to the moment they walk out after their appointment. We strive every day to show you just how easy and enjoyable your dental visit can be.  

One specific aspect of our office that separates us from other dental offices is that we offer dental crowns, from start to finish, in one visit. We do this with CEREC technology and the newest equipment currently available. We also are fully equipped with the necessary equipment for laser procedures and have our own dental CT scan right here in the office. Patients can expect a personal yet modern approach to their treatment plans.

We want to answer all of your questions and establish a relationship to take care of your current and future dental needs. Please feel free to message/email/call us!


I am a huge hockey fan and a dentist with a degree in general dentistry from USC, with a focus in guided implant surgery and the latest technology that cad cam dentistry has to offer.

Why should patients choose you as their provider instead of others in the area?

I am a certified CEREC dentist which allows me to perform crowns in a single day. Digital x-rays are more comfortable and the patients win when they don’t have to receive injections more than once or when they don’t have to wear inferior temporary crowns.

What Do Our Patients Say

The service here is always great! From the moment you are greeted at the front desk, to the moment the Doc is doing his work and until you are leaving the office with a sense of knowing you didn’t just get robbed like you do from other dental offices who only seem to care about is money. You can watch a movie while getting work done, how cool is that!! It makes the time fly and by the time you know it your all done. They have all high-tech machines and can do your x-rays there instead of having to go elsewhere. The office manager Jane really knows how to help explain treatment and is overall a really nice person. She just makes understanding why you need the work done and is completely honest about it. She truely cares about you and making you feel completely comfortable. Dr. Rennaker does amazing work and doesn’t rush. I would definitely recommend this place to anyone looking for a dentist.

Bob R., Tarzana

As I told the doctor after my visit, I have NEVER had a dental appointment which I actually enjoyed until Dr. Rennaker. That’s not hyperbole; it’s fact. I went in for a deep cleaning, dreading it. In less than 40 minutes, my whole mouth felt brand new. And the procedure was absolutely painless thanks to local anesthetics and topicals. I could not recommend Dr. Rennaker more strongly. Even if you have a dentist who you go to currently, give Dental Plus Tarzana a shot. You’ll make the switch just like I did. Thanks for saving my tooth Doc.

Arthur S., Tarzana

My wife and I went in to see Dr. Rennaker because I was intrigued by his “high tech” exam. Well – in my wife’s case, he found two potentially troublesome problems that had been previously undiagnosed by other dentists – and was able to make the necessary fixes before they progressed into something much more serious. In my case, the doc offered a better, and MUCH more affordable, solution to a long-term problem that I’d mostly ignored due to the extremely high prices I’d been quoted elsewhere. I’m a big fan!

Dave B., Winnetka

Dr Rennaker and his staff were fabulous! So professional and efficient! We found them online needing an emergency one day crown repair. I could not have been more pleased. The procedure was painless and I walked out 3 hours later with a high quality permanent crown indistinguishable from my real teeth! Extremely impressed and happy with the work. Bonus: very military friendly. I would highly recommend Dr Rennaker!

Scott G.

Very professional, clean, and out in a timely manner!!! Such an amazing experience. The staff is by far the most professional and friendly I have ever met. Such a positive, comfortable environment, that I didnt want to leave! I was very impressed with the modern equipment, as it truly benefits me as a patient. After one visit, I can honestly say that I found the perfect dentistry!

Robert M.

The staff and doctor were super nice and professional. The visit was great for my 4 year old which was awesome since he doesn’t like the dentist much. For me it was great getting options on braces and the assistance was amazing.

Genevieve M.

I have a major fear of the dentist. I actually have an HMO, so my insurance is not accepted at Dental Plus. But I would rather pay cash to see Dr. Rennaker than use my insurance and see someone I am not comfortable with. He made me feel relaxed, and was very patient with me. The other staff was super sweet as well. My whole family goes to him because of this!!

Julianna B.


Dr. Rennaker is truly amazing. I had 4 wisdom teeth extracted and it was the best dental experience I’ve ever had. He is great at what he does, explains everything thoroughly and is very gentle. The whole staff was great, and the office was very state of the art.

Julie S.

I am so glad that my wife found Dental Plus in Tarzana. We are treated so well, and the level of care that this team takes to make you feel comfortable and welcomed is 5 star!
