Your best bets are either going to be blue pearl in tampa, they have a glider specialist however they are extremely pricey.
Or Marcum road clinic in Lakeland http://www.marcumroadvet.com/
who does have experience with gliders but uses blue pearl for consultations. Prices are much more reasonable with the benefit of getting information and assistance from blue pearl without their prices.....however she will drive diets down your throat for a good while before actually addressing the issue you came for even if you are well versed in diets and dietary information. Once you get past the diet bs she's a good vet and has surgical experience with gliders.
I have recently switched to Marcum road vet despite the dietary debates she insists on having, I'm confident in her abilities and determination with things she may not be experienced with yet.
