We were visiting family in Las Vegas when our 11 month old became sick. I scrambled to find an urgent care that was open on a Friday afternoon the day before Christmas Eve. Two urgent cares I called had a wait of over 2 hours and did not specialize in children's medicine. I found this establishment on Google and was extremely pleased!
We visited this urgent care the day our son fell ill and 3 days later for a follow up. The wait was about 45 minutes for walk in and 30 minutes with an appointment.
They get 4 stars instead of 5 because the wait time was the same whether we had an appointment or walked in and because some of the staff were pleasant but not overly nice.
