Dr. Blackwood opened his first family medical practice in Canada in 1983 and has practiced continuously ever since. In 1994 he was recruited by Tidewater Medical Group (now part of Sentara), and he and his wife, Catherine, along with their ten children, moved to Chesapeake. When TMG merged with Sentara, Dr Robb and Mrs. Catherine decided to return to private, independent practice, which they believe allows them to offer their patients better care.
