Welcome @pmracc33186, I saw your comments in the Key's to a Successful Doctor's Appointment (https://connect.mayoclinic.org/comment/1054031/) and think it's great to be a strong advocate for your healthcare. I wouldn't give up on Mayo as it can be difficult to get appointments just due to the availability and number of patients looking to make an appointment. I have no experience with TLE but I think Leonard @jakedduck1 may have some experience or suggestions. Mayo Clinic also has some information on Epilepsy care that may offer some suggestions - https://www.mayoclinic.org/diseases-conditions/epilepsy/care-at-mayo-clinic/mac-20350102.

Another option you might want to investigate is the Mayo Clinic Care Network - https://www.mayoclinic.org/about-mayo-clinic/care-network. The Mayo Clinic Care Network is a network of member hospitals (https://www.mayoclinic.org/about-mayo-clinic/care-network/members)
The Mayo Clinic Care Network helps keep care local by providing guidance and answers to many questions that might otherwise require a referral to a specialist. In many cases, this spares patients the expense and inconvenience of additional appointments and unnecessary travel. If specialty care is needed, patients can be seen by local providers or referred to Mayo Clinic.
