My husband has pneumonia, so as soon as I started coughing, I made an appointment at the new Marque Urgent Care on Alicia Parkway. It was so easy to start an account and get in quickly. The place is beautiful and the staff was so friendly. Check-in was fast. The PA was so knowledgeable about my asthma and gave me meds to keep it from becoming worse. I feel so much better after only 2 days.They contacted me by phone and text to make sure I was better. Love this place!

So amazing these caring souls that work here! I came in last minute with my daughter and in the kerfuffle of illness and getting her there on time we forgot her ID. The appointment I had originally was at 6:30 and they close at 7. We didn’t get back there with the ID until 6:50. The angel at the front desk called me to see if I was still coming! They helped us thoroughly, thoughtfully and with incredible kindness. Thank you immensely.

Everything was awesome. I was in and out before I knew it appointment was easy with the help of my insurance help and I would be happy to direct them to you’re A+ Urgent care because they are always there for me when I need anything from them and that makes a person feel good knowing that there’s a office open when other offices aren’t and can’t make an appointment when you need it I depend on them when my office is full with appointments and they’re always there and that makes me happy🤗
