There are many different certificates. These are older and we can discuss the recent certificates when you call.  I am very discreet due to all the pirating that goes on with the web. Heart certifications are done by a cardiologist.  I believe mine is one of the top in the country. 

The latest heart certifications were done May 6, 2010.  The latest Hip and Elbow are scheduled October 5th 2010.  I keep them updated and you get copies at time of delivery.
