Meet Daniel Marzec
Qualified sports massage therapist and the face behind Muscle Relief Therapy in Swansea.
Built on Sport.
Driven by Results.
Hi, I'm Daniel Marzec — the founder and lead therapist at Muscle Relief Therapy in Swansea. I've spent the last several years working at the intersection of sport and soft tissue therapy, and I founded this business because I believe everyone deserves access to the same quality of care that professional athletes receive.
Before founding Muscle Relief Therapy, I worked as a sports massage therapist supporting semi-professional and grassroots sports clubs across South Wales — providing squad treatment sessions, match day therapy and individual injury management for players in rugby and football. That environment was fast-paced and demanding, and it gave me an instinct for quickly assessing what a body needs and treating it effectively.
Today, I work with a wide range of clients at my Swansea clinic — from competitive Hyrox athletes and rugby players to runners, gym-goers and people simply trying to manage the physical demands of everyday life. Whatever brings you in, my approach is the same: listen properly, assess thoroughly, and use evidence-based techniques that produce real, lasting results.
My qualifications:
What You Can Expect
Personalised Care
Every session starts with a full consultation. Your treatment is tailored to you — never a one-size-fits-all approach.
Evidence-Based
I use techniques grounded in anatomy and current research — not trends. You'll understand what I'm doing and why.
Real Results
My goal isn't just to make you feel good for an hour — it's to create lasting improvements in how you move and feel.
