Marta V Kosinski, MD

Dr. Kosinski at UCSF is awesome. She has been our daughter Sierra’s (12 month old) pediatrician since birth. Dr. Kosinski is very patient and attentive. As new parents, my wife and I appreciate her taking the time to address all of our questions. We couldn’t ask for a better pediatrician!

We absolutely love Dr. K and couldn’t imagine a better pediatrician.
She’s everything you want — knowledgable, patient, unparalleled bedside manner, and very good about returning phone calls.
Oh, and what’s more — when you can’t see her, you’ll love all of the other doctors just as much!
I wish she didn’t work where she does, but whatever… she’s worth dealing with a less-​than-​ideal doctor’s office.
Our boys have a doctor crush on her, I’m sure of it. As long as that’s not weird. If it’s weird then they just think she’s one attractive pediatrician. :)

We love our son’s pediatrician, Dr. Marta Kosinski, from the UCSF/​Mt Zion Pediatric group. Our son is always happy to see her and very relaxed around her. I’ve had many moments where I’ve called her with paranoid questions and she is always so patient and never makes me feel like I am asking dumb questions or over-​reacting. She has been very accommodating and non-​judgemental of our wish follow an alternate (and less intensive) vaccine schedule. I know many of the pediatric practices are very strict about following the recommended vaccine schedule, and parents often struggle to find a practice that lets them do this, so we feel very fortunate. Dr. K was the first pediatrician that I met with before having our son, and I knew right away that she was the right fit for us!
