- effective and respectful patient consultations
Common complaints
- reports of rude, unprofessional, or overworked front desk staff
- difficulty reaching the clinic via telephone with calls allegedly transferred to an answering service permanently
"Dr Passarelli and his staff in the office are absolutely wonderful, helpful, and kind, but the front desk lady at the testing center, Tina, is the absolute worst. She is extremely rude, not friendly, and seems like she has no clue what she’s doing and laughs and carries on personal conversations instead of helping the people waiting at the window."
— Dr. Rachele Idelman blog (quoting patient feedback)"He is arrogant but that's because he really does know what he is doing. I think he is the BEST on the Gulf Coast. He has saved many a life including mine."
