About Us
Avant Wellness Systems Ltd (Avant UK)
Avant Wellness Systems Ltd is the UK subsidiary of the California-based medical technology company specialising in advanced photobiomodulation devices for clinical use. Avant UK offers veterinary therapy lasers designed to deliver fast, consistent, and evidence-informed treatments that support post-surgical recovery, wound healing, chronic pain management and musculoskeletal rehabilitation animals.
Avant Class 3B lasers are cordless, lightweight, handheld devices built for efficiency in modern veterinary practice. The LZ30 ProZ-Vet combines red (637 nm) and infrared (808 nm) wavelengths, providing effective treatments using a choice of numerous built-in presets. These features allow vets and rehabilitation teams to target inflammation, stimulate tissue repair, and reduce pain with reproducible clinical results. The LZ30 Revi-Vet adds a 405 nm violet wavelength to the red output, offering additional benefits for surface tissue healing, dermatological conditions, and microbial support making it particularly valuable for complex or compromised patients.
In the UK, Avant’s distribution is managed by HewMed Distributors, run by Julia and Chris Hewitson. Julia, an ACPAT Category A veterinary physiotherapist with over 40 years’ of human and animal experience, provides clinical guidance and practical training to ensure safe and effective integration of Avant laser therapy into veterinary and allied practices.
Avant UK is committed to promoting photobiomodulation as an everyday, clinically effective tool that improves patient comfort and recovery outcomes.
