Dr. Quintero is a top tier, very involved physician. She's extremely concerned about her patients, and always includes parents in her decisions. She looks to my husband and me for accurate information, as well as ideas on what we think is going on, and makes sure we are included in all decisions. Our son is incredibly complex; she's the reason we were able to bring him home when we did (at 14 months he absolutely would've stayed in the ETCH PICU longer than that if it hadn't been for Dr. Q's ventilator expertise and confidence in our ability to care for him. She's also the reason we've been able to keep him healthy since he's been home. She's a brilliant, kind-hearted physician, and we are so incredibly lucky to have her on our team.

Dr Quintero answered my questions, and even my daughter's questions about her upcoming procedure. She took her time with us, explained test results, goals, and didn't rush through the appointment. Professional and courtesy given.
