"Finally found a Doctor who listened to all that I was experiencing and going through. Cared, listened and tested for what I asked for and gave me options to fix and gave me hope that the headaches I've had for 3 and a half years might actually go away when my primary Dr. Said I didn't have allergies. I would highly recommend the Allergy and Asthma center. Their staff was kind and courteous. And above all they listen with compassion!! Thank you!!"

"Very friendly staff & convenient location if you're going to school (I'm not, just saying). I got some allergy testing done and I will be going on allergy shots that they make special for my exact allergies. Neat!"

"I'm starting to think there's a new breed of doctor (and office) much better than we've had in the past. Redundancy of information on forms is still ridiculous (how many times do I have to write my name and address?) but some things I guess are going to take longer."
