They open Monday through Saturday @ 7:30 am and close anywhere between 6:00 & 7:30. However, the early hours are for drop of for cleanings, day visits etc. The actual vets don't start until 9:00 or so and stop about 6:00. We are usually lucky and if we plan ahead for exams and shots can get a Saturday appointment, but I usually have to plan weeks in advance. Sunday is emergency only. However, I don't think I have been to one appointment when they have been on time. Anywhere from 15 - 30 minute wait, but it is close to home and most of the vets are very nice except for one whose "bedside" manner leaves a bit to be desired, so I request that we see anyone but him.
