Does this clinic do check ups for turtles?

I am pretty sure they do but not certain. I would call and ask.

Dr. Stachmus sees a large variety of tortoises and turtles, and even owns a diverse assortment personally.

Yes they do

Depends how exotic the turtle is. Turtles are some of the toughest reptiles. If it eats poop eyes look okay that's the check up you'll get

Yes, they even have one in the waiting room.

Seems like the would

I saw turtles in the office.
