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.
