Lymphedema is a chronic and often misunderstood condition that affects millions worldwide. For patients, finding the right care can be life-changing, and for healthcare professionals, becoming a Certified Lymphedema Therapist (CLT) opens doors to a rewarding and impactful career. At the heart of this career path is CDT certification, the gold standard in lymphedema training.
If you’ve ever wondered what CDT certification is, why it’s important, or how to become a Certified Lymphedema Therapist, this guide will walk you through everything you need to know. We’ll also share how Norton School of Lymphatic Therapy—a global leader in lymphedema education—can help you achieve your professional goals.
What is CDT Certification?
Complete Decongestive Therapy (CDT) is the internationally recognized gold standard for the treatment of lymphedema and related disorders. It combines several essential techniques, including:
- Manual Lymph Drainage (MLD): A specialized hands-on technique that stimulates the lymphatic system.
- Compression Therapy: The use of bandages, garments, and wraps to reduce swelling and maintain progress.
- Exercise Therapy: Movement strategies that support lymphatic function.
- Skin and Nail Care: Preventing infections and maintaining skin health in lymphedema patients.

When a clinician completes the required training and meets certification standards, they earn the credential of Certified Lymphedema Therapist (CLT). This designation signals to patients, clinics, and healthcare organizations that the therapist has the advanced knowledge and hands-on skills to provide evidence-based lymphedema care.
