Dr Roi Cheng, DIANM

Principal Chiropractor/Clinical Director

Dr Roi graduated from the prestigious chiropractic course in RMIT university with a Masters in Clinical Chiropractic with distinction. He has practiced at Croydon Chiropractic Centre since 2013 and has transitioned to become clinical director since July 2018. Dr Roi's interest in chiropractic started when he discovered how much it helped him personally, and feels very honoured to now be able to help many others in the Croydon community to achieve spinal health and wellness.

In 2023, Dr Roi completed his post-doctoral studies and has passed the board examinations to be inducted into the International Academy Of Neuromusculoskeletal Medicine as a Diplomate and has thus been conferred the title of DIANM. He is only the second chiropractor in Victoria to achieve this title and the 10th in the whole of Australia. His studies have given him specialised training in MRI interpretation, and in diagnosing and managing complex pain syndromes, migraines, dizziness, balance disorders and degenerative conditions of the spine and extremities. He is passionate about providing evidence based, outcome driven chiropractic care to help patients achieve their goals.

Dr Roi is the proud husband of Joan and proud pet-dad of Owen the schnoodle. In April 2024, Dr Roi and Joan welcomed their first child, Aria Grace Cheng into their family. In his spare time, Dr Roi enjoys keeping active, enjoying a good meal with friends, and likes dabbling in technology. He is always happy to have a chat and loves a good laugh!
