5.0

I was initially unsure of Dr. Atallah but he has proven himself to be a caring, considerate doctor that really goes the extra mile. He researches my spectrum of medical conditions and regularly suggests tweaks to improve the efficacy and safety of my Rx regimen. He’s very on top of messaging and medication requests. I feel heard with him and my care is collaborative.My initial reservations surrounded his very thorough, beyond the book onboarding procedures. It was a barrier to care while I was in acute need but I recognize the need to mitigate liability and confirm health status. If you’re in dire need of care he might not be the best choice because of the time needed for his onboarding procedures but if you’re stable I highly recommend.
