To my knowledge, Mercedes USA does NOT "certify" independent repair facilities.
What you're looking for instead is a facility preferably owned by a former Mercedes dealership mechanic with plenty of official training, plus ownership of STAR equipment and access to WIS. Hiring mechanics with this experience can be almost as good.
Personally, I wouldn't let a mechanic without said qualifications check the air in my tires.
