The staff are very friendly, knowledgeable and always willing to help. They can be very busy at times but that's to be expected when you're dealing with such a large organisation. There is not much I dislike about this clinic. It has been great for us so far and we've had no issues with them whatsoever. We've been going to Sonic for a few years now and have never had any problems or complaints from our daughter. She's been seeing Dr. K for her yearly check-up and she's also seen the dentist there as well.
