The phone number for Dr. Weiss is 301-299-4142.
 
For the person moving to the DC area, you're moving into a prime area for
ferret vets.  Among some of the vets I use for various things are:
 
Dr. Charlie Weiss (Potomac Animal Hospital) 301-299-4142
Dr. Roger Hart (Kingsview Animal Hospital) 703-971-9292
Dr. Tom Kawasaki (Old Bridge Animal Hospital) 703-690-2580
 
Good luck!
 
Amy, Dave and Sarah (and their gaggle of giggling ferrets)
RIP Ian, Elektra and Claudia
