Unlock Your Smile's Full Potential in Pasadena

Founded over 40 years ago by Dr. Allan Charles and Dr. Wilson Morishita, Foundation Dental Specialists has a rich history of providing trusted, top-notch periodontal care to patients in Pasadena and the San Gabriel Valley.

In 2022, we expanded the commitment we have made to our patients by offering Endodontic specialty care (root canal treatments) as well. Our specialists work in a synergistic way to provide better, more comprehensive care to our patients than we would be able to achieve working independently.

Our new name, Foundation Dental Specialists, reflects our commitment to working with our patients to help them build the strongest support possible for a healthy smile. Whether it is through preservation and strengthening of natural teeth, or the replacement of failed teeth with dental implants, Strong Smiles Start Here.

Dr Lee and his assistant were great. They explained every procedure and it all turned out fast and efficient. The office staff is also great. They handled all billing accurately and quickly and were very accommodating working around my busy schedule.

I got a root canal treatment completed by Dr. Nerissa Lim and she was amazing! She has such a calm and professional demeanor, and you can tell that she focuses on quality over quantity. I felt very comfortable throughout the procedure and she always made sure I was doing ok. I highly recommend her for root canal treatments!

I would highly recommend this office for dental work. I have had oral surgery in the past and was extremely nervous. Dr. Weightman was so professional and caring. She made what would have been a terrifying experience at another office easy and pretty pain free. I appreciate her gentleness and ability to relate to my needs. The office staff was very friendly, caring, considerate and professional. The office was very clean and modern. A definite thumbs up for this practice. Thank you so much Dr. Weightman.

I can honestly say that this was one of the best dental experiences I've ever had. I was having a cyst removed from my inner cheek, and Dr. Weightman took the time to explain the procedure in detail. I didn't experience any discomfort - even after the procedure. Dr. Weightman was very warm and kind and made me feel very comfortable. I would definitely return to Foundation Dental.

I have been a patient of Dr. Charles since May of 1980. I have received excellent treatment and were it not for the care that i have received over the years i would have lost most of my teeth as result of the periodontal damage. Nancy has been my dental hygienist for the better part of 15 years and continues to give me excellent care. In summary I will never change Drs. as long as I live.

You really feel like you are in a clean, friendly and professional environment. I am always leaving satisfied and I refer them to all friends and family.

This practice is rated way above my experiences with two others in terms of professionalism, efficiency, staff and thoroughness. I came here after a botched 3 implant expensive surgery that had failed within a year. The procedure here was less painful, more caring, much more skillful and performed with way more precision. Lots of follow ups to monitor the procedures, and even follow up phone calls after major parts of the procedures. Glad that I discovered this group. Complementary parking in a quiet neighborhood of Pasadena just off the 210 Fwy. Kudos.

I went yesterday for a wisdom tooth removal and everything went great. Dr Weightman is the best dentist I’ve ever worked with. She is professional, fast, precise and able to put you at ease while pulling your tooth out. Everyone in the office is super friendly and it’s easy to find parking. I hope I’m not going to need them for a while but if I do I will definitely come back here.

This was my first experience with needing periodontal work, and I expected that it was going to be painful or at last uncomfortable for weeks and weeks from the way people talk about it. I was pleasantly surprised at how little physical discomfort was involved. I had two procedures with Dr. Weightman. First, an infected tooth was removed, then three months later an implant was put in its place. Dr. Weightman took the time to answer all the questions I had and checked in over the phone after hours each time to make sure I wasn’t having any unexpected symptoms. Both times, the healing process was straightforward, so clearly the procedures were well done.
