    A friend of mine told me about Dr. K, at Gateway, so I am a very apprehensive patient, and I thought I would try this dentist...Well my experience was wonderful, he was gentle, kind and through and I would highly recommend him to anyone in the area I felt Dr. K was caring, and extremely knowledgeable.


    Have been going to Dr. K at Gateway Dental group for past 3 years. I have such a good experience with Dr. K's work as well as the Gateway Dental staff I have sensitive teeth and Dr. K always made sure that I get special care because of that, he is very caring and knowledgeable . The staffs working at this office are very friendly and helpful. Lena at front desk always welcomes patients with smile .Dental assistance Grace and Katie are so friendly and professional. I have been recommending Gateway Dental to all friends, family, and co-workers for past three yeas and I do recommend Gateway Dental service to all people who are reading this review.


    I had a very good experience during my visit to the Gateway Dental Group. Dr. K was very professional , knowledgeable and caring, his staffs were helpful and pleasant. I recommend Dr. K to my family and friends.


    This dentist is great. I have been coming to Dr. K for 4 years and let me tell you that he is the best dentist I ever had. He is very nice and caring and will take his time to explain to you your treatment and problems that you might have. I will continue to get my dental treatment and 6 month check ups with Dr. K. Hopefully in the near future my children will also come to him. Thanks Dr. K for all the great work you have done for me. : )


    After a bad experience at another Bay Area dentist I finally found a practice I can feel relaxed about going to. I am so happy with the care that I have received at Gateway ! Dr. Kay is amazing, knowledgeable and really takes his time to understand your needs/concerns as a patient. After telling him my concerns with being numbed with a shot he assured me I wouldn't feel it. Amazingly I didn't feel a thing!! The front desk knew me by name after just one visit and the entire staff is fantastic. I wish I could give more stars!


    I had a great experience at this facility, he dentist was gentle on my sensitive teeth and staff are all professional. I am taking my kids to them and they both just started braces. I do recommend them to my family and friends.
