TMJ Mastery:
Principles, Applications
& Disc Discplacements
Welcome to TMJ Mastery, a 3-day live workshop designed for RMTs and Manual Therapists. Our comprehensive program equips you with the skills to effectively treat TMJ dysfunction. Join us to enhance your practice and earn your TMJ treatment certificate.
What sets TMJ Mastery Apart:
A unique interactive visual study of the progression of the Articular Disc Displacements based upon the lifelong research of Dental Prof. Dr. Jeffrey Okeson of the U. of Kentucky. Utilizing illustrations (with permission) from Dr. Okeson's textbook, we focus on a frame-by-frame comprehensive study of the 4 stages of Anteriorly Displaced Discs, bringing this understanding to our treatment planning, client by client. Can restorative measures be expected, or are we reducing further progression? What are the simple-truths that are often concealed within this complex joint and its dysfunction? How does our client measure success? And most importantly, what do we do with our hands when TMJD shows up?
Mastery Defined
The "Y" in Mastery is very important to me: "A lifelong process acquiring the tools to be a trusted authority on a given subject, cultivating effective skills rooted in real knowledge, AND the humility informed by knowing every answer brings many more questions."
- John W. Corry
What participants have said:
“This is the first time I have used your education in clinic and I knocked it out of the park! Your class was so hands on. Which is amazing. This is the most confident I have ever felt doing TMJ work!”

"Filled 3 whole days talking about a small area with the time management skills, precision and delivery of a ninja... then gave us assessment forms, brochures, and referral forms. I love you dude."

"Great Course. After being a Dental Assistant for 9 years John explained TMJ in a way no one ever did in that industry or the massage world. I leave with a much better understanding."
Nicole N.

"As a person with a learning disability, every aspect was well presented and completely understandable. Honestly, the best workshop I've taken where I can go back to my clinic and feel completely confident in what I've learned."

John W. Corry, RMT
Nova Scotia - Canada
Since 1992, the topic of TMJ Dysfunction has been a driving focus in my career. I am a full-time RMT in a clinic setting DOING the work. The side-hustle TMJ Mastery represents my passion for "passing it on"; collaboration and effective outcomes light me up! Word of mouth has fuelled a capacity schedule for 30+ years. Dentists, PTs, DCs and MDs have patients that tell them about my work - and they refer more patients. For over 15 years two SLP's, focused on spoken-voice and singing, have had a rewarding referral relationship with me. This opened a further niche supporting university vocal-music students and Profs (and a few grad-performers) of opera, as well as Shakespearean stage actors. Further study in laryngeal positioning and tongue tension resulted. The SLP connections led to referrals from ENTs at a hospital's Vocal-Function Clinic. Now living in Nova Scotia, when not in clinic, I can be found hiking with my wife - Kathy, mountain biking on trails, shooting B/W photography and being silly with grandchildren.
