I last came in for my consultation back in December and immediately felt welcomed. The clinic is very clean and modern. It can be busy but to me I took that as a positive sign, that just made me feel like I had made the right choice as a busy clinic means they’re doing something right. Since my skin is something I tend to be insecure about, I’m always a little tentative talking about it or having it looked at. However, my experience here made me feel so comfortable. I felt that Dr. Sajic actually listened to what I was telling him and helped me find a solution that was best for both my skin and my routine. I didn’t feel rushed and was never pressured to purchase products I didn’t need, something that I find has always happened with other doctors I’ve seen. The clinic staff are not to be forgotten either, from the second I walked in to the second I left they made the experience so much better. Big thanks to the team here, I will definitely be coming back!
