Great team of dentist, hygienist, and office staff. The best part about this team is that they genuinely care about your oral health. None of that pressure sales non sense I used to experience at franchise dental offices. This is a result of quality service and reputable experience. Would highly recommend. Going on 6 years with this office.

After receiving horrible service from two other dental offices, a friend recommended Dr. Liswi. From the very beginning, the experience was outstanding. The staff was professional, welcoming, and quick to assist me. Dr. Liswi was incredibly patient — I didn't feel the needle at all. When he worked on my tooth, I felt absolutely nothing. If you're tired of bad dental experiences, do yourself and your family a favor and go to Dr. Liswi's office.

Came in for an exam and cleaning, and I'm beyond impressed! Never had a dentist take the time to explain and answer my questions like Dr. Liswi, and honestly the whole team is amazing from the front office to the chair side manner. Will be telling my family about this place for sure!

I brought both of my daughters here for their braces. Dr. Siddiqui has been so kind and warm with both of them. One of my daughters needed a lot of work and attention, he's been patient and very skilled. I wouldn't take them anywhere else. It's been an overall excellent experience. The office staff is also very friendly.

Dr K and the staff are amazing! I had another provider who recommended a root canal and I was like, 'Hell no'. I went and got a second opinion with the team at Soboh Liswi and I couldn't be more grateful. Dr K suggested a porcelain crown and continued use of a night guard. His bedside manner is like no other and I didn't feel a thing! Amazing! Easy parking and great front office staff as well. Highly recommended!

Who the heck says they love their dentist?!? I DO!! Dr. Liswi has been incredible! He cured my TMJ when nobody else could. We had an exchange student chip her tooth on a Saturday and they not only answered my voicemail on a weekend, he drove all the way from OC for an emergency visit on a SUNDAY. Both experiences were practically PAINLESS. The staff, from the front desk to the hygienists to the billing are ALL friendly, kind, and so gentle. The whole team is incredible and they deserve 10 stars!

I cannot recommend Dr. Liswi and his team enough! I had significantly worn down my teeth due to years of grinding, and Dr. Liswi completely revamped my smile. He shows he cares about his patients by thoroughly explaining every procedure. The atmosphere in the office is wonderful — Liz and the other dental assistants are so friendly, sweet, and helpful. I've finally found my permanent dentist and will definitely be returning with my family!
