Meet the Team

Sandra Jefferies

Director and Physiotherapist
An active member of the community, Sandra started her career at Sir Charles Gairdner Hospital after graduating from Curtin University in 1988. She completed a Postgraduate Diploma in Sports Physiotherapy in 1993 and quickly realised that her heart lay in private practice.

Power Physiotherapy was the realisation of this dream, born in 1997 to empower people to take control of their own health and wellbeing with the right treatment, tools and advice.

Passionate about her profession and its ability to positively shape the lives of patients, Sandra has worked extensively with National Sport teams, including being selected to look after the weightlifters, para power lifters, wrestlers and badminton players at the Queensland Commonwealth Games in 2018. An Internationally credentialed McKenzie Therapist and having successfully completed level 1 and 2 courses for the Dean Watson Headache Approach, Sandra believes in furthering her knowledge and keeping up to date with the latest physiotherapy methods.

At Power Physiotherapy, Sandra loves treating patients with a wide range of injuries and makes sure that each patient not only understands their condition and treatment plan but has the confidence to achieve their goals and shape their own future.

Stefano Vinci


Stefano is an experienced member of the Power Physiotherapy team, who on graduating from Curtin University with First Class Honours, started his career in musculoskeletal physiotherapy in private practice.

His fascination with the human body has driven his passion to pursue work in the health industry where he can truly make a difference.

At Power Physiotherapy, Stefano treats a broad patient base with joint and mobility issues, soft tissue injuries and post-surgical care. His attention to detail in using evidence-based practices and hands on therapy, helps to build confidence levels in his patients as they return to better health.

Stefano is committed to furthering his knowledge by always being involved in Continuing Education in Physiotherapy. One highlight in 2016 was completing the Level 1 Dean Watson Headache Approach, fulfilling his keen interest in the treatment of headaches. Stefano is skilled at making a diagnosis and creating individualised goals to help you return to full function. With Stefano’s focus on rehabilitation and exercise therapy he finds getting people moving again after any injury or surgery, incredibly rewarding.

Darren Cheah


Darren joined the team at Power Physiotherapy in 2021. Darren completed his studies at Curtin University Western Australia and has previously studied a degree in Anatomy & Human Biology at the University of Western Australia before realising physio was his calling.

Darren has been keen on furthering his education outside of university and has already completed his level 1 Dry needling and GLA:D program training, focussing on the rehabilitation of patients with Osteoarthritis of the Hip and Knee. He continues to attend regularly other professional development courses to best formulate personalised and evidence-based recovery plans for his patients.

Darren is passionate about guiding patients through their whole journey of recovery from pain and injury. He aspires to achieving patient goals, not just getting people back to how they were before but feeling and performing better than ever! Darren loves helping patients get back to what they love doing and is particularly passionate about treating all types of sports people, runners and gym-goers, having several years of experience in training in the sport of powerlifting and being an avid amateur hiker.

Outside of the clinic you might bump into Darren enjoying long walks along the beach, at the gym or dancing with friends!

Katharine Andrews


Kat’s interest in the human body led her to completing two degrees at Curtin University. The first being Human Biology (Preclinical) followed by a Master of Physiotherapy. This enabled her to apply her anatomical knowledge of the human body to a practical approach with physiotherapy.

Kat is a physiotherapist with a passion for helping patients recover lost function and return to the activities they love and achieving their goals. A people person, Kat builds great rapport with patients and has the knowledge to explain movement impairments, the physiology of injury management and the healing process to patients in clear and simple language.

Kat has a keen interest in sports and physical activity and has participated in gymnastics, athletics, roller skating, roller hockey, field hockey, cricket, volleyball and AFL. She’s currently preparing for her first half-marathon in 2023 with a view to completing a full marathon within the next year.
