  • Brenda Mettetal
    I have been under the care of Dr. Timothy Crouch for about 5 years for allergies and asthma. Never have I had a relationship with a Dr. and staff that was so personal and yet so professional. I have received excellent care for my health issues. Dr. Crouch and his staff are a part of my family now!

    I have been a patient of Allergy, Asthma and Sinus Center under the care of Dr. Douglas for as long as I can remember (maybe close to 10 yrs). Dr. Douglas and his staff have always taken such wonderful care of my children and myself. Dr. Douglas is a wonderful doctor who cares about his patients. He has always taken the time to listen to all my concerns and try to help in any way that he can. Thanks to all AASC employees for doing an exceptional job each and every time!
