Experienced respiratory physiotherapists

Kim Mellor

Kim graduated from the University of South Australia in 2005 and began her career at the Lyell McEwin Hospital, working across cardiorespiratory, general medicine, surgical, neurology, musculoskeletal, paediatrics, orthopaedics, acute rehabilitation and hydrotherapy, as well as clinical education.

She joined Respiratory PhysiO2 in 2011 and has since completed extensive postgraduate training in cardiorespiratory and musculoskeletal physiotherapy. Her focus is giving people the right tools to self-manage their condition and building their confidence with exercise and movement.

Outside work Kim keeps up with three very active children and loves anything outdoors.

Kylie Johnston

Kylie has worked as a respiratory physiotherapist across general hospitals, adult and paediatric intensive care, private practice and pulmonary rehabilitation in Tasmania, New South Wales, Western Australia and South Australia.

She was awarded a PhD in 2004, an NHMRC Research Fellowship in 2013 and a Churchill Fellowship in 2017. Her research looks at how people with lung conditions can be more active, do the things that matter to them and better manage breathlessness.

Kylie joined the practice that is now Respiratory PhysiO2 in 2008 and values working with both adults and children with lung conditions. She also teaches and researches part-time, and outside work enjoys yoga and walks in the bush or at the beach with her family.

Feng Tam

Feng moved to Australia from Beijing as a teenager in 1985 and graduated from the University of South Australia in 1992.

She built her early career in rural and private hospitals around Adelaide, working in intensive care, cardiac rehabilitation, pulmonary rehabilitation and chest physiotherapy. In 1997 she completed a Postgraduate Certificate in Cardiorespiratory Physiotherapy, followed by further training in cardiac rehabilitation (Brisbane) and pulmonary rehabilitation (Perth).

Feng has also trained in acupuncture and cancer rehabilitation.

Yuka McMahon

Yuka began her career as a paediatric physiotherapist after graduating from Kanazawa University, Japan, in 1990. Her interest in respiratory care led her to complete a Bachelor of Science in Cardio-respiratory Care at the University of Arkansas for Medical Sciences, and she worked as a registered respiratory therapist in the USA.

Back in Japan she worked in cardiac rehabilitation and community aged care before moving to Adelaide in 2013. Yuka became a registered physiotherapist in Australia in 2015 and joined Respiratory PhysiO2 the same year. She practises at Hazelwood Park and, every second Friday, at our Morphett Vale rooms.

Lara Graham

Lara graduated from the University of South Australia in 2015 and has worked across several metropolitan Adelaide hospitals.

She has worked in chronic disease management with a cardiorespiratory focus in the Northern Adelaide Local Health Network, where she helped develop culturally safe exercise classes and cardiorespiratory assessments. She has also supported veterans returning to civilian work and serving Australian Defence Force members with injury recovery.

Lara joined Respiratory PhysiO2 in 2023. Outside work she loves travelling, rock climbing, Brazilian jiu-jitsu and a good book with a cup of tea.

Portia Matto

Portia graduated from Flinders University with a Bachelor of Health Science and a Master of Physiotherapy in 2025. During her studies she worked as a sports trainer with Fulham United Soccer Club, gaining experience in injury management and rehabilitation.

She holds additional qualifications in Pilates instruction and dry needling, and has a particular interest in respiratory and musculoskeletal physiotherapy. Outside work Portia enjoys time with friends and family, good coffee and all things health and fitness.

Joseph Melahrinos

Joseph is usually the first person you'll speak to at Respiratory PhysiO2. As Office Manager he looks after bookings, GP referrals, Medicare GPCCMP, DVA, NDIS and HICAPS claims, and keeps the clinic running smoothly so the physiotherapists can focus on your care.

He also looks after the practice's technology, including this website and our online booking, and is happy to help if you're not sure how to book, what to bring or how a rebate works.

Outside work Joseph is a keen gym-goer and golfer, throws a decent dart, and likes a long walk with a business podcast in his ears. He also builds apps and websites in his spare time.
