5 /5 LD Luna: Dr Zonjy took over after my former doctor, Dr. ATA from Frisco, retired. Dr Zonjy is thorough and competent. I am satisfied with his concern and treatment for my absence seizures. His staff is competent and friendly. As Dr Zonjy is taking over from another doctor, his calendar was full and it did take 3 months to get an appointment. I have seen him three times in a year.
