Best doctor's office I've found in Vegas.
I've been to a total of 3 general practitioners in Las Vegas, and it's been hard to find one who seems to really care about my well-being. Finally I went to Dr. Conger at the recommendation of a co-worker, and she has been awesome. Whatever my complaint, she takes it seriously and runs every necessary test to ensure there's nothing more serious going on. She also sits down with you and really gives you time to discuss whatever you are there for.
They do many of the tests at the office, so you aren't always trekking across town to get lab work done.
Dr. Conger has also referred me to two specialists, and both have been good. I like knowing that she isn't just referring me to a friend, as some doctors in Las Vegas do (ahem, Jateko Family Medicine).
I highly recommend Dr. Conger and the Diagnostic Center of Medicine. The 4-star rating reflects just a few little issues - moderate waiting time, not taking my friend's insurance, and one accidentally deleted appointment. Over all, though, it's pretty awesome!
