'I must say this is the BEST dental office I have been into in my life. I was referred here by 4 different people. Walking in, I was in a great deal of pain with a horrible infection and swelling beyond belief. They took me in last minute and made the process so easy. From the sweet front office staff, to the nice lady who took my X-rays, and extremely knowledgeable and caring Dr. Grewal, all his staff during the surgery, and Eduardo for making sure I was taken care of after pre/post op. They all went above and beyond for me, making me feel so comfortable up until my surgery and after! Dr. Grewal even called me after surgery to check in on me, ensure me that that surgery went smoothly, and repeat aftercare instructions again. Thank you for helping me when I was in need. You all made the process exceptionally easy and painless during what couldve been a very stressful and painful time in my life. Thank you for everything. I am actually looking forward to my follow up! And future things I have planned here. I appreciate you all so much.'
