Onicca completed her OMT-1 course through the South Africa society of Physiotherapy. The OMT course is an evidence-based course grounded in the biopsychosocial management of patients with neuromusculoskeletal pain and dysfunction.

She then worked as a Senior Physiotherapist at Philadelphia Regional hospital from 2017 – 2019, where she gained experience in multiple fields of physiotherapy.

She is passionate about many areas of ongoing specialisations that physiotherapy offers, with a special interest in treating and managing neuromusculoskeletal, sports and orthopaedic conditions. Her passion has led her to volunteer at the Mamelodi Sundowns academy while completing her final year in 2015. She got the opportunity to travel with the U17 team to China for the Gothia Cup Tournament in 2017 as the team physiotherapist.

Onicca Nong gained exposure in private practice through locums at various private practices and private hospitals, gaining simultaneous experience in treating and managing neuromuscular, sports, ortho, paediatric, ICU, cardio-pulmonary conditions etc. This inspired her to open her own private practice in 2018.

She is currently registered for a post-grad diploma in sports and exercise physiotherapy with the University of Witwatersrand and she's part of the Mamelodi sundowns FC medical team.
