Dr Pak always takes her time and answers all my questions thoroughly. I never feel rushed. The staff is always pleasant too. The clinic is rather a long commute as I first started as her patient at her office which was much closer to home. I dont mind the commute because I feel I am getting good care and attention. Together we set healthy goals for the next appt which I like. Thank you.
