“Thoughtful and patient doctor. Took the time to hear me out and really listen to what I was experiencing. Gave me many options and talked through them extensively. Left feeling like I was in good hands.”

“Dr. Moussai is amazing! Such an excellent listener! I have a very complex case and a lifetime history of serious issues. His evaluation was thorough and compassionate. He did not rush. He told me, “Jump in whenever you want and let me know if something seems like it doesn’t make sense.”
He also recommended that I follow up with my neurologist to ask why I have the temporal lobe epilepsy if they if they’re able to determine that. I never thought to ask that. My temporal of epilepsy diagnosis only came in last year after nine years of seeing different neurologist, and not being satisfied with the results.(Can we say woman patient, anyone?)”

Please allow about 30 minutes to complete this form. Your responses will help your provider prepare for your upcoming appointment.
