I'm not sure where in Seattle you live, but the practice I go to is pretty nice. It's at NE 45th and Union Bay Pl/Sand Point Way (right by University Village Mall, the medical building across the street from Baskin Robbins - note: the Judy's Book map comes up wrong, so you may want to mapquest).
The clinic is run by Dr. Mindy Blaski, who is board certified in family medicine & geriatrics. I think she's taught or led a research team, or something along those lines, at UW. She seems to be a very laid back, caring person. She's my husband's doctor. I usually see Jennifer King, who is the nurse practitioner there, and she is very nice and capable, much better than some HMO doctors I've seen.
The office just had one receptionist, so you usually talk to the same person - so they don't act like strangers every time you call. I also appreciate you don't have to go through a silly voice prompt menu (e.g. press 1 for directions, ...).
Other people seem to have been coming to this office for quite some time (they bring flowers they grew for Dr. Blaski, etc.), which is a good sign that this is where you can build a relationship with your care provider.
Another nice thing about this clinic is that the lab is located right upstairs, so you can just walk up to the lab if full blood work is needed. And Victoria, I think that's her name, who runs the lab by herself is very nice as well. (Good phlebotomist! Good at poking/finding your vein - I should know; I've donated lots of blood and the tissues around my veins have been hardened so it's hard to get to my veins for most young phlebotomist. Victoria is an old pro)
The only thing I would change about the clinic is the fact that a nurse asks me what I'm allergic to each time I go in. I kind of feel like "wasn't that the whole point of filling out those paperwork in the beginning?!", but I guess it is better to be sure than sorry. :-/
