  • I just had a root canal this morning with Dr. Johnny Kim, and it was the most painless—and actually enjoyable—experience. Dr. Kim worked hard and succeeded in saving my molar, which was a tough case. He is amazing, and it’s clear he is highly skilled and well trained. The entire staff was very caring and checked in often to see how I was doing. The office is also very nice and clean, which is another plus. Highly recommend all around!

  • I had such a great experience at this dental office today. The staff and dentist were extremely helpful and caring, and they made me feel comfortable the entire time. I went in feeling a bit sad, but their kindness and conversation really lifted my spirits. The service was professional, and they truly care about their patients. I would definitely recommend this office and will be going back anytime I need dental care!

  • Everything was very clean, and the hygienists were sanitizing everything regularly. Appointments ran on time, and I was able to get out earlier than expected. They also had a TV on the ceiling to watch during my appointment. They also had contactless payment, and let me know up front that there would be no cost associated with my visit based on my insurance. I’ll definitely be back! This is how all dentists should be!

  • Great service! I went in for a consultation with the endodontist, and it was quick and very informative. They were understanding and gave me options. The front desk was excellent—polite and super helpful!

  • Had an overall excellent experience, jade the hygienist was very personable and excellent, and the dentist was sweet as well. Did a regular check up (after a long time) they assessed everything and I felt as though they were very thorough with my care. Will be going back for sure and keep up the good work.

  • My first visit to Tend was pleasant. I needed to get my crown replaced they told me my options and the best way to address my situation. They explained my coverage and out of pocket expense, everything was made clear. Above all the atmosphere and the staff were very knowledgeable and efficient. Looking forward to my next visit.
