Deccan Dental Origins

Nanjapa named his practice “Deccan Dental” as an homage to his roots. He was born in India and lived most of his childhood in its southern peninsula of which the Deccan Plateau is a large part. The name “Deccan” is der ived from the Sanskrit word “ दक्षिण ” (dakshin) meaning “south”. It covers at least 8 Indian States and is located between three stupendous mountain ranges, the Eastern Ghats (Sahyadri), the Western Ghats (Mahendra) and the Blue Mountain (Nilgiris) where they meet at the Doda Beta peak. The southern plateau is r ich in eco and cultural diversity and offers striking contrasts in respect of race, language and social customs of the north. The blend of different languages, traditions and cuisines gives this area a culture and heritage that is both unique and intriguing. It has a colorful history dating back centur ies. And the next time you take in the aroma of the spices, the defining character istic of Indian cuisine, know that most are from the verdant spice plantations of the Deccan Plateau. The only way to take in this breathtaking ensemble of variety is to visit the Deccan Plateau.

Dr. Nanjapa was born in India where he earned his dental degree from MAHE, India. He moved to the US in 1998 and received a Masters in Dental Biomaterials at University of Alabama, Birmingham in 1999. Dr. Nanjapa went on to complete a three year program in Advanced Prosthodontics from University of Illinois, Chicago. After 4 successful years in private practice and teaching at College of Dentistry, Chicago, he moved to the Bay Area in 2007. In early 2011 he left the private practice he had been working at in San Francisco to start “Deccan Dental” here in San Mateo. He also maintains a part time faculty position at College of Dentistry, UCSF. Today he continues to live in the Bay Area with his wife, Hina and daughters Meera and Saira.

This dental office is amazing. My doctor was Dr. Saboowala. Due to my exam results i have to visit them several times. I liked their approach. I had to do a lot of work and they referred me to different doctors, who were also amazing and professional. Doctor Saboowala was very patient and try to do all work correctly. I had to do several crowns. Some crowns come back from lab and Doctor felt they were not fitting correctly, she just simply send them back to redo them. I want to mention the staff. All assistants were friendly and receptionist always promptly reminded about my appointments. Very good experience for me. I would definitely come back to them.

Dr Nanjapa has been my dentist for a very short time, but I’m really happy I chose him. This weekend I broke a tooth in half. I left a message with their service and within a short period he called me back and agreed to meet with me later that afternoon. I wanted the tooth pulled. As a stage 4 lung cancer patient there is no reason to try and save teeth at this point. He got it. Only too often dentist want to save the teeth at all costs but he understood and was able to remove the tooth without debate. I appreciated that. I would highly recommend him if your looking for a new dentist.

Dr. Nanjapa is a thorough and customer friendly dentist. My family and I decided to switch and utilize his services after getting care from a local dentist in Fremont for a few years. He is open and honest.

We are very satisfied with the care he has provided to my family. My four year old daughter really enjoys visiting and getting care from him..

I did not see dentist for a long time. Today I saw Dr. Saboowala who is Dr. Nanjapa’s associate. She did very great job for me. She did my 3rd molar extractions without pain and she did 2 fillings for me which look like my nature teeth. I highly recommend to see her. She is very nice and patient.

My dad got a filling done from Dr. Nanjapa. Dr. Nanjapa is an awesome dentist. He put my dad at ease. He is the best dentist I have ever seen My dad is visiting me from India and suddenly developed pain in several of his teeth. My dad didn’t have any insurance, but their office worked with us on the payments. Dr. Nanjapa’s office felt like a family-owned office. It’s a small office with great expertise. I am very very impressed with their hospitality and welcomeness! I highly recommend Dr. Nanjapa for any dental needs.

Dr. Nanjapa was fantastic and put me at ease. He was very nice and definitely did his best to make sure I was as comfortable and pain-free as much as possible. The best dentist I’ve ever been to. His staff also was very nice and helpful. Their number 1 priority is making you feel comfortable, welcome and pain free.

The place is super clean with modern equipment. It has a pleasing and comforting feel to it unlike other dental offices which give me anxiety as I enter. The overall experience was so great that I am sure I won’t go anywhere else.

This dentist is wonderful. I went in as a new patient and was impressed by Dr. Samir’s work. He is not only well knowledgeable but sincere and patient.

Soon my husband and my son became his patients. The office is nice cozy and friendly. Great for accommodating appointments.

I had not been to the dentist in 20 years! For good reason, they are scary! However, I finally bit the bullet and through a friend found Dr Nanjapa. Wow…

Don’t even know how to put it into words…

Somehow he has made me so comfortable going to the dentist that after my first 4 visits I opted to have future visits do more than one tooth, and I would sit in the chair for hours, literally hours, relaxed the entire time. No pain, seriously, and I am a big baby.

He is very fair on cost and works with you. I would recommend him to everyone. Hope you give him a try. After 20 years my horrible teeth are beautiful, I smile bigger, and no longer have that sense of impending doom a week before the appt.

Dr.Nanjapa is awesome! I’ve had work done by him in the past and he did a fantastic job! I wish I lived closer so I could go to him for all my dental work. I highly highly recommend him.
