About us

Our Practice

Think Physio (formerly Dandenong Valley Physiotherapy) has been operating at Mulgrave Private Hospital (formerly The Valley Private Hospital) and servicing the local community for over 20 years. Originally located near the Emergency Department of the hospital, the practice grew from a small clinic with only 2 physiotherapists consulting to what it is today. With this expansion came the need for larger rooms and so we made the move across the road into the consulting suites opposite the hospital in early 2013. This has afforded us a much larger area to consult our patients and has allowed us to set up a new boutique gym area, allowing us to provide such services as Clinical Pilates and gym based rehabilitation from injury/surgery.

Our clinic currently has 4 physiotherapists and one myotherapist consulting, giving our patients the flexibility to book appointments before or after standard business hours during the week and also availabilities on Saturday mornings. We also have 4 very friendly reception staff working at the clinic to ensure that you are completely looked after from the time you make an appointment with us.

Most importantly we are a fun loving and energetic group that always has the best interest of our patients at heart. Our physiotherapists are always available via phone or email should you have any questions regarding the health of yourself or a loved one. So give us a call today and let us help you get started on the road back to work, back to sport and back to life!!

Always remember... if in pain...THINK PHYSIO!

In an earlier life, Ralph played football for Melbourne (Under 19’s & VFL reserves), St.Kilda (VFL reserves), Sandringham (VFA) and finally for St.Kilda-Sth.Caulfield (VAFA). He was a state representative in both the VFA and VAFA.

Kal Peiris

Kal graduated from Melbourne University in 2005 and began working at Think Physio in early 2006. Over this time Kal has mixed full time work at the practice with additional positions at local football (AFL) clubs and the Under 12 Victorian Rugby team. This work has led to a special interest in knee and shoulder conditions and sporting injuries in our younger athletes.

As a junior, Kal was a keen basketball and soccer player as well as a Victorian representative in Touch Rugby during his university days. He continues his passion for sport these days as a loyal St Kilda fan and a huge cricket fan (he secretly goes for Sri Lanka)!!
