Any of these links below will give you a list of known reptile vets, sorted by state.
Don’t wait to contact a reptile vet! It is common for many people to have to drive an hour or two to get to a reputable reptile vet, but it is worth it. There is nothing better than talking with someone experienced with reptiles, and knowing that they understand and can diagnose and treat your animal properly.
In Michigan, I recommend Dr. Wayne Beasley, located in Lansing of the Cedar Creek Veterinary Clinic.
