Dr Michael Walczak B. V.Sc (Hons)

Owner
Michael graduated from the University of Melbourne in 1979, then worked in mixed practice in Mildura and Seymour. He returned to Melbourne in 1981 and worked at Monash Vet Clinic which specialised in greyhounds and movement disorders of show dogs. He has been at Doncaster Veterinary Hospital since 1985.
Michael is a great believer that children benefit from growing up with pets and following on from this, pets become good companions through our entire life. The human/pet bond can be as strong as family ties.

Michael's 'grand'-cat Frank, a Ragdoll, also visits regularly when his daughter Clare is on holidays and loves to beat up Oscar. In his spare time he is a 'tragic' Melbourne AFL supporter, loves good food, wine and conversation, can't get enough time for golf and longs for lazy holidays and seafood at Noosa beach. Michael is a grandfather to 1 with another on the way.
