My husband had balloon sinuplasty here at the Loop location on Jackson 12 weeks ago. All the P.A.'s and staff that we dealt with were wonderful. Had great results with no more snoring or breathing issues since the surgery. I would highly recommend this facility in particular and this surgery for anyone suffering from sleep apnea and failed rhinoplasty's. His breathing is so much better and getting a much better night sleep along with his energy back from breathing properly. GET IT DONE! ITS WORTH IT
