Our North Ryde Chiropractors & Physiotherapists

He is the current Sports Chiropractor for the Australasian PGA, and earlier in his career worked with professional tennis players on the WTA tour. Patients see him for spinal diagnosis, long-running pain, and rehabilitation that has stalled.

Damien trained at Macquarie University, completing a Bachelor of Science in Anatomy and Physiology followed by a Masters of Chiropractic Science in 2002. He later added a Masters of Exercise Science (Strength and Conditioning) at Edith Cowan University. That second Masters explains how he practises: the adjustment or needling settles the pain, and the strength work that follows is what stops it coming back.

His work outside the clinic runs on the same approach. He has delivered onsite chiropractic, physiotherapy and pre-employment screening at Linfox and Coles distribution centres, and co-founded 4D Health and Performance, a performance facility on Clarence Street in the Sydney CBD built for elite athletes and corporate patients.

In golf, Damien is the current Sports Chiropractor for the Australasian PGA, servicing tournaments including the Australian PGA Championship and the Australian, NSW, VIC and WA Opens as part of the tournament medical team.

His earlier professional sport work was in tennis, where he treated WTA players Peng Shuai, Zheng Saisai and Zarina Dyas at events including the Australian Open and Dubai Open. Closer to home, he oversaw physiotherapy and strength and conditioning support for Eastwood Rugby from 2019 to 2024.

For a patient walking into the North Ryde clinic, all of that means one thing: the assessment is the same one a touring professional gets. A full movement screen, a specific diagnosis, and a plan built to finish, not to keep you coming back weekly.

Dr Liam Quinn is a Sports Chiropractor at Spectrum Healthcare in North Ryde. A former elite rugby union player, he spent four years treating professional and representative rugby union, basketball, touch football and golf teams before moving into private practice. He is SIRA approved for workers compensation care and trained in spinal decompression.

Liam holds a Master of Chiropractic and a Bachelor of Chiropractic Science from Macquarie University, and still plays rugby for Northern Suburbs. That matters in the treatment room. He has had most of the injuries he treats, and he knows the difference between soreness you can train through and pain that needs proper diagnosis and management.

His sessions combine spinal and peripheral adjustments with dry needling, cupping and exercise prescription, working toward a clear return-to-play or return-to-work point rather than open-ended treatment. He is also trained on the clinic's BTL Spinal Decompression table, used for disc injuries and sciatica that have not responded to hands-on care alone.

Away from his own patients, Liam has mentored junior chiropractors in anatomy and diagnostic technique, and spends winter weekends providing sideline medical support to junior representative rugby teams.

Lauren Marshall is a chiropractor at Spectrum Healthcare in North Ryde. She holds a Master's degree in Chiropractic from the University of Johannesburg and ran her own practice in Johannesburg for four years before relocating to Australia in 2021. She pairs chiropractic care with DMA Clinical Pilates and the GLA:D Back Program for persistent lower back pain.

Lauren's clinical interest is biomechanics: working out why a joint or muscle is overloading, not just where it hurts. Across South Africa and Australia she has treated elite athletes, children, and patients with everything from acute injuries to pain that has persisted for years. That range taught her that the same diagnosis rarely needs the same plan twice, and her treatment reflects it: adjustments, soft tissue work and advanced myofascial dry needling in whatever combination the case actually calls for.

Where many chiropractors finish at the adjustment, Lauren keeps going. As a DMA-trained practitioner in both reformer and mat Pilates, she uses Clinical Reformer Pilates to load a recovering spine gradually and precisely on spring resistance. That progression from treatment table to reformer is the difference between feeling better and staying better.

For persistent lower back pain she also delivers the GLA:D Back Program, a structured education and exercise program built on clinical guideline evidence, which she trained in at Macquarie University.

Holly Drain is a physiotherapist at Spectrum Healthcare in North Ryde. She holds a Bachelor of Health Science in Physiotherapy from Auckland University of Technology, spent more than five years in rural private practice and with rugby union teams in New Zealand, and competes internationally for New Zealand in Olympic weightlifting.

Rural practice is a fast education. With no specialist down the corridor, Holly assessed and managed everything herself: acute sporting injuries, post-operative rehabilitation, and the chronic conditions that fill a country caseload. That breadth shows in how she works now. Assessment first, done thoroughly, then a plan that combines manual therapy, the Mulligan Concept, dry needling and progressive exercise.

The weightlifting matters too. Holly programs strength work daily for her own international competition schedule, so the exercise she prescribes is specific and properly dosed, not a printout of generic stretches. Patients rebuilding after surgery, and lifters wanting a clinician who understands the barbell, tend to end up on her list.

Her rugby years at club and semi-professional level added the sideline skills to match: acute injury management, advanced sports taping, and the judgement to know when an injury needs urgent referral. She is WorkCover accredited for workplace injury rehabilitation and has completed the APA's Shoulders: Simplifying the Complex certification.

Rebecca Funnell is a physiotherapist at Spectrum Healthcare in North Ryde. She graduated with Distinction from the University of Otago in New Zealand and is the current Wests Tigers Women's Physiotherapist, managing player injuries from the sideline through to return to play. She competes in Hyrox, so the training loads her patients carry are ones she knows firsthand.

Sideline work sharpens clinical judgement. On game day Rebecca has minutes to decide whether a player is safe to continue, and that discipline carries into the clinic: every plan starts with an honest assessment of what the injury can tolerate today and a staged path back to full load.

In the treatment room she combines manual therapy with personalised exercise plans, using the SFMA, a structured movement assessment that traces pain back to the movement fault driving it, alongside dry needling where it will speed things up. The goal is always the same: get you moving properly again, then make the result hold without standing appointments.

Her NSWRL Orange Shirt Trainer accreditation and weekly involvement in elite women's rugby league keep her acute injury skills current, and her own Hyrox competition schedule keeps her honest about what realistic training progression looks like.
