What Our
Patients
Say

"I had my wisdom teeth removed by Dr. Fernando and his team (shout out to Sam, who is also excellent). I could not have asked for a better experience both physically and emotionally. Huge thank you to the whole office for their kindness and expertise. Thank goodness all four wisdom teeth are now out of my head, but if I ever had to do it again, I'd go back to Gateway!"
Bronwyn R.
“ I saw Dr. Fernando for an implant, he was very quick and made me feel so comfortable. The whole staff was incredible and Andrea was very thorough with the whole process. Highly recommend!”
Abby T.
“ Everyone from the staff at the front desk to Dr. Fernando were professional and very warm. I appreciated that they took great care to make sure I knew what to expect during prep and after and made sure I didn’t have any questions. The surgery was so quick and they made sure I was okay before I left with my rider. I got a lot of information for my healing and feel great after following their instructions. Thank you Tina and Dr Fernando and everyone else.”
Jessica M.
"Dr. Nolan pulled my wisdom tooth and was the most compassionate doctor ever!"
