Join us for the MASO 2021 Annual Session in Rio Mar, Puerto Rico from November 4 – 7, 2021!

The Annual Session will be an in-person meeting of 300 MASO doctors and practice staff at the Wyndham Grand Rio Mar Puerto Rico Golf & Beach Resort.  The Annual Session will be a combination of education, networking with colleagues and vendors, and Fun in the Sun activities – including a Golf Outing, a Fun Run/Walk, a Welcome Reception and Saturday afternoon beach and poolside lunch and entertainment.

Did we mention that Flip-Flops are required?  With the meeting set in beautiful Puerto Rico during November, temperatures are in the 80’s and the water is warm and inviting!  It’s no wonder that so many flock to the island each year for some winter sun.

The Annual Session theme is ‘Technology for Achieving Desired Results.”  Keynote speakers, discussing the latest technology in orthodontic patient care, will highlight the morning doctor sessions.  Practice staff will be offered training in several different areas to help improve overall workflow.
