Dr Farhadi shows you on xrays what your issues so you can understand. He tailors his fiber and probiotics suggestions to your circumstances. Grateful to have a dr who takes the time to explain and for testing me for lactose intolerance which no one had done before.

Amazing doctorWelcoming staffGreat nurseGood facilities But why oh why oh why was i kept waiting for over an hour?? And why couldnt the staff say “ sorry, just want to let you know we are running behind” and maybe:: “so if you would like to take a walk or go have a coffee in the lounge here is a chit for a free coffee.”It doesnt feel good to be ignored - that basically communicates that MY time is not valuable - and therefore that I am not valued… Even though you have done everything else to brilliantly communicate and make sure that every patient is well cared for- from the valets, to the security, to my-chart etc. It would not require much!!Thank you!
