I haved worked with Dr Yoganathan for many years in a drug and alcohol service. He is an approachable Doctor,very chatty and friendly with staff, and i would say that at times, this could be mistaken as overly friendly to people that don't know him. He is very knowledgeable in his role, and has always made time if needed to discuss patient issues. Dr Yoganathan is very passionate about his work ,and keen to teach others his vast knowledge. He has a good approach with his patients, kind and compassionate/. He has also supported me through a difficult time in the past.
