My first RE was chosen because of it was right across the block from one of my work offices. (It saved me parking costs!) Then my office moved out of that building and so I had to pay for parking. The clinic was 45-60 minutes from home, though. Oh, if I was going from one office to another, it would be a 10-15 min trip to the RE.

Then a few months later, I left that clinic to one that was not in Seattle but in Bellevue, WA instead. So it is 30 min drive from work or from home. (Nice compromise, I guess.) The drive to the clinic isn't so bad since I'm usually doing the reverse commute compared to everyone else on the roads. I'm happy with my current clinic so it all worked out.
