What Others Are Saying
"It's been three years since I was certified in lymphedema therapy. Although I have been practicing as a CLT daily, I have not done any theoretical review in that time. Going through this course was like being back in the classroom. It has been tremendously helpful to review it all again!"
K.L., PT - Caldwell, ID
"I took the Norton School course 2 years ago and I've been feeling like I needed to review the fundamentals again. Taking this online course is like hearing Steve lecture in the classroom. I would highly recommend it to any practicing CLT."
S.R., PT - Port Chester, CT
"I took a couple sections to prepare for the LANA exam. I would say it was well worth it, especially the amount of detail covered in the Anatomy area."
A.M., OT - Los Altos, CA
"I was truly impressed with how well Steve's lectures are integrated with the detailed slides. This is a great review tool for any therapist looking to brush up on the foundations of CDT!"
B.G., COTA - Chicago, IL
"I'm so glad there is finally an online resource for lymphedema education! I took several of the sections and found them to be very worthwhile. They have short exams at the end so you can see how well you actually know your stuff!"
C.T., PTA - New York, NY
"It's about time! I've been asking for this for years. I really don't have time to travel to physical course locations, so having this comprehensive program available online is just what I needed. I will definitely recommend that my colleagues take it!"
