Dr. Bergman along with Danny and Robin are so good at their jobs: insanely thorough and very competent. Several teeth implants and periodontal appointments with the trio pros always ended up with smiles and a feeling of "I'm glad I had it done". Smile is so important as one gets older. Got so many compliments on my white and healthy teeth. Thanks...

The staff at at Ajay B. Setya,etc., have been wonderful, kind, understanding and courteous. They have taken the time to explain the procedures in detail and put my mind at ease. Dr. Bergman especially has exhibited knowledge, professionalism and skill and has gone the extra mile to ensure an excellent outcome. She went the extra mile to ensure that the medications Im taking do not adversely affect the meds necessary for my implant procedure by consulting with my medical doctor/oncologist. The staff is professional and thorough and encouraged me along the way. Also, Daniela did a gentle and thorough job cleaning my teeth plus the entire staff was courteous and extremely helpful.

Was just recently seen by Dr. Setya for my pre-op appointment. He is so kind and professional. Analyzed my specific dental problems and gave me his absolute attention during our chat. I could not help but hear his kindness towards his staff while waiting to be seen. His calm is infectious. This is the BEST practice for dental implants or Periodontal issues. Highly recommend this office.

HIGHLY recommended. Dr. Reshad and his team are amazing (especially Aracely). I went in today for a consultation and received the most comprehensive, methodical, and honest evaluation in my 20 years of dental challenges. Dr. Reshad explained his diagnosis and recommended course of action clearly. His bedside manners and attentive listening skills are excellent as well.

The staff, from the receptionist to technician to billing point-of-contact to Dr. Bergman, could not have been more friendly and welcoming. They thoroughly explained what was being done at the time it was being done, and extensively discussed what to expect for upcoming surgery, from the procedure to after care and costs.
I cant recommend them highly enough.

From the moment I stepped in, the front office greeted me with warmth and a big smiles on their faces, immediately making my anxiety melt away.
My hygienist, Nihad, was outstanding, extremely thorough and deeply attentive. Throughout the cleaning, he consistently asked how I was doing and explained exactly what he was about to do next. That steady, communicative approach ensured I always knew what to expect.
When Dr. Reshad came in for the checkup, he reviewed what Nihad collaborated seamlessly. Dr. Reshad did an examination of his own with a level of attentive care with remarkable professionalism. He clearly explained what I needed to do and why, articulating the rationale behind each recommendation in simple and patient friendly way. That thoughtful clarity helped me understood the importance of moving forward.
Its increasingly uncommon to find a dental team that brings this level of care, dedication, and passion, everyone I have met at this office is so attentive and I feel like such a positive environment, theres qualities can feel hard to come by. Yet, this office exemplifies exactly that: compassionate, clear, and committed service to patients from start to finish.

Dr Setya and Dr Reshad were both so knowledgeable and patient in answering all the questions I had. I never felt hurried or rushed, even though my appointment was the last of the day.
I came into the office nervous about the state of my perio/dental health, and the drive home was as if I had just spent time with friends. Calm, supportive, and professional. There is no other office to work with for your perio health.

Dr. Setya and staff are incredible! He was able to perform a difficult procedure without issue. The recovery was quick and the results proved to be fantastic. I almost didn't go through with the procedure because of a poor experience I had with a periodontist in San Clemente... I wish I was referred to Dr. Setya initially. His talent is undeniable, his interaction with patients is unparalleled. Do not hesitate to make an appointment.

Dr. Setya and his office staff are second to none. My first visit started with a tour of the office. Everyone, especially Dr. Setya, have the best manners and make you feel like a special guest. All of my appointments were on-time and I received not only a treatment but also an education on how to care for my oral health. Dr. Setya and the hygienist were very thorough on all treatment. It was an excellent experience for me and I recommend Dr. Setya to all that are looking for a competent and ethical dentist.
