I was very impressed with Dr Cho and his staff! Very organized and efficient. Ashleigh is amazing! Totally on top of everything. I had crown lengthening done and the experience was great! No pain at all and Dr Cho walked me through everything so I knew what was happening and what to expect next. Ariel and Dr Cho work great together! They gave me post op instructions verbally and Ashleigh also gave me instructions on paper so I know how to care for the area when I get home. I will definitely refer my friends and family to Dr Cho in the future!

I am so happy with my results after Dr. Cho performed a gum surgery on me to fix my gummy smile. He made the process fast and painless and made sure to explain everything thoroughly to me. I would definitely recommend visiting his office!

Dr. Cho was thorough, quick, clear, and direct in his exam and assessment of our daughter, visiting for a possible labial frenectomy. He has earned our full trust. Highly recommended. The front office is efficient as courteous. The entire operation is a caring, effective, and efficient well-oiled medical machine :-). Congrats!

I have been going to Dr. Cho for at least the last 5 years, and I highly recommend him and his practice to everyone I know who's looking for a quality periodontist. After many years of getting the run-around or getting too short "perio quadrant scaling cleanings" from traveling periodontists working with NO oversight from the dental providers they partner with, I finally realized that I needed to find someone with extra expertise and integrity. I feel Dr. Cho has both. I have had regular cleanings, deep cleanings and 1 implant surgery with him. Very happy with his care!

Dr. Cho cares about each patient and recommends the right procedure and considers the cost to the patient. His work is thorough and answers all questions asked. He also asks questions to understand why they are visiting his practice and any background before making any recommendation. He made me feel very comfortable and I felt he was the Periodontist for me..
