Franconia, VA-based family practitioners Brett Wohler and Andrew Wise are switching to concierge care, leaving 5,000 Northern Virginia residents with some important questions about their healthcare. The two doctos will join a national doctors' network and will charge each patient an annual retainer of $1,500. In return, the physicians will offer perks such as round-the-clock cellphone access, same-day appointments and time to accompany their patients to specialists. The move follows a nationwide trend that is a reaction to what some doctors see as the excesses of managed care.
