About Elsternwick Osteopathy

Elsternwick Osteopathy began its days many years ago high up a marbled staircase, round a corner and down a hallway of a classic 1980’s brick office block in Glen Eira Road. Today however, Elsternwick Osteo finds itself… well, still in the same place, but that’s great because Mike and Chelsea the Osteos love being here!

We share this great space with a wonderful Pilates studio, a hyperactive landlord and an environment dedicated to making you feel superb. We’re Osteopaths that want to get to know you. We want to hear about your day at work, even if it’s been crap. We want to hear about your kids needing to be in 3 places at once and your annual effort to weed the garden on a 35 degree day. And tell us again how you took 5 wickets in 6 balls 20 years ago and you’re still rolling the arm over. Because all of these experiences add to the story of your pain.

We really like you, but we like your pain more. And we want to get to understand your pain really well, take it out for dinner and put it in a cab on its own for an early night. We’re good at listening, asking, assessing, treating and helping you manage your pain. We’re safe, we’re hands on and we’re waiting to hear all about you.

Osteopath – Dr Michael Santamaria

Michael Santamaria - Elsternwick Osteo

Michael Santamaria attended RMIT University and obtained a double degree in Applied Science and Osteopathic Science.

Michael treated at the Carlton Football Club for 5 years and has tutored students at RMIT for a couple of years. Michael has also worked for various touring teams including treating the New Zealand All Blacks in the 2003 Rugby World Cup.

Michael is a footy tragic and loves his Old Dark Navy Blues and embarrassingly admits to travelling to watch his beloved Carlton play interstate (3 times last season). But he adds that he has a wonderful interstate record and has carried his Blues to victory several times in the past decade. He is very enthusiastic with Carlton’s chances in 2024. He loved the final 3 months of last season but wants to go 2 steps further next year…okay that’s probably a little too much for a simple practitioner bio…

He loves getting down to Blairgowrie in the summer and as a father of 3 he is now officially obsessed about lawn. He recently did his first ever lawn renovation – what even is a lawn renovation?
