OKLAHOMA CITY, March 28, 2011 /PRNewswire/ -- Graymark Healthcare, Inc. (Nasdaq: GRMH ), the nation's second largest provider of diagnostic sleep services and an innovator in comprehensive care for obstructive sleep apnea (OSA), reported financial results for the fiscal year ended December 31, 2010.
