"Love the clean office and staff was amazing. I found my new dentist. :)"
–Jessica G.
"One word: Amazing! Dr. Lin and his staff are professional, clean and very informative. They make sure you get what you wanted done and understand everything before you leave. They have gained my trust and I will continue to come here and recommend friends/family to come here as long as they are in business."
–Richard N.
"Dr. Lin and his assistant are truly amazing. I love how they are so gentle and treat us like people instead of just a number. You can see they truly care and have so much patience with each of my family members. I have numerous problems and TMJ, so Dr. Lin was very sensitive to my needs. He let me take breaks and made me feel comfortable. If you are looking for a dentist that cares and is not about taking your money then look no further. Sun Smile is the place to go!"
–Anne W.
"SO HAPPY! Our insurance changed and I hated to look for a new dentist. I looked at reviews for all the ones offered in our area and relieved that our experience was so good. The staff are genuinely nice and want the best for you. The waiting room, patient area, and bathroom were super clean. The chairs were very comfortable and I was given Netflix to watch during my cleaning. I was surprised by how much time and attention I was given by Dr. Lin. He was my primary caregiver through the experience. I would see my old dentist at the very end of my exam for a couple minutes. The hygienist was so kind and fun to talk with. My husband had an appointment right before mine and he had an equally great experience. We'll be sticking with them as long as we can."
–Melody K.
"They are amazing and so personable."
–Amanda M.
"We have been coming for a few years but with the new dentist in the office we are more excited about services. He is super friendly and he does great with kids. Even after getting a tooth pulled out my daughter still wants to go back."
–Erika A.
