Patient Testimonials

 This type of procedure is usually thought about rarely as it is usually a terrifying experience that we try to avoid at all coasts, but Dr. John and his faithful team at Pinnacle Endodontics came through with shining colors. They say that they try to make you fell as comfortable as possible, that they want you to feel like a king, and that's just what they do. I would recommend them to any and everyone, even the Queen of England! They make the experience more enjoyable then it normally is!! A++


 I''ve been without health insurance for the past 6 years and I''ve had the same tooth ache for just as long. I now work 2 full-time jobs, 80 hours a week, and on my only day off, I drove over 40 miles round-trip to have you work on my tooth. I did this because I was assured by my new Dentist (Dr. Chung) that you and your team were the Best. You did not disappoint. Your reputation, character, and workmanship far EXCEEDED my EXPECTATIONS. Your approach and communication relieved my stress and in return, allowed me to relaxed and have a painless procedure. Your team was also kind and warm. From the moment of my 1st phone call to schedule an appointment, to exiting your office, and receiving follow up phone call''s throughout the week to check on the status of my discomfort. Your team has demonstrated COMPASSION and PROFESSIONALISM and made a nervous situation for me, a POSITIVE EXPERIENCE. Thank you so much!


 I cannot say enough good things about Dr. John and his staff. I was terrified before the procedure but after completing both visits, I am no longer afraid and would see Dr. John again for any dental issues. Thanks for such a great experience!


 Thank you for taking such good care of me!  Dr. John and Joan - you made the process of getting a root canal a surprisingly pleasant experience.  The snuggie was a very nice touch.  I am relieved to feel back to normal with my tooth and sleep through the night again.


I was hesitant about having this procedure done since I have had a root canal previously by another Dr years ago.  This was one of most pleasant dental experiences I have ever had.  

Dr. John and his staff were very concerned about my comfort level at all times.  He took his time explaining each step during and after the procedure as well. 

I will absolutely refer my friends and family to Dr. John.  Thank you for making an unpleasant experience very positive!


My 2 visits were the most wonderful dental experiences I have ever had.   Best dentist/dental staff in Socal!


I am very pleased with Dr. John and his staff. They are very professional and caring, especially in regards to the comfort of their clients. Your follow up emails and phone calls were greatly appreciated. It's obvious you really care about your clients. I am very fortunate that my dentist's office referred me such a qualified Dr. I will definately refer friends to you when the opportunity presents itself. Thank you so much!


Dr. John is the most caring and thorough endodontist. His expertise is unsurpassed. Having several root canals in the past, my experience with Dr. John was absolutely the best. He uses the latest equipment and has a passion for his field. I would highly recommend Dr. John to dentists and anyone seeking an endodontist.


Dr. John and his Staff have the most caring personalities.  I walk in there with severe anxiety and as soon as Dr. John starts to speak to me the anxiety starts to subside.  His assistants are just as caring as he is.  I will never go anywhere else to have this type of dental work done.  I am very blessed to have this office available to me anytime I need them.  Thank you Dr. John for all your caring and your expertise.


I was very impressed with Dr. John and the staff. I appreciated the follow ups and feel like I got the best treatment possible. Thank you!
