A Montgomery County principal who was running pricey private seminars, including one scheduled at his school on a weekday, shut down his consulting company Friday after The Examiner discovered that his side business may violate the Board of Education’s code of ethics.

Since incorporating the business in 2006, Moreno “Mo” Carrasco, principal of Rockville’s Richard Montgomery High School and Maryland’s 2007 High School Principal of the Year, has held several Breakthrough Principal seminars at schools around the region, often scheduled during the week.
