The doctor made slight when requesting referrals for specialists with "your taking blood thinner you don't need a vascular doctor" or based on my age I don't need the specialist.

Doctor Tsang treats me, as a patient, with the same care he would treat his family with. He's absolutely the best doctor I've ever had. He's brilliant, on point, understands the issues exceptionally well and is very supportive - truly cream of the crop.
