Dr. Charles Pullen wasn't going to include boarding in his plans but was later convinced it could pay a good portion, if not all, of his monthly mortgage. And it has done just that more than a few times in the last year. His architect came up with the idea of putting the boarding and dog park on the second floor because there wasn't enough space to keep all ancillary services on one level. A boarding manager who's also a certified obedience trainer runs the boarding facility and manages the staff.
