“Dr. Morrissey and his staff are AMAZING! If anyone out there has a little kiddo (or not) that is in need of an ENT doctor, I highly recommend you see Dr. Morrissey. Him and his team are extremely knowledgeable and you can tell they love what they do. From the initial appointment/consultation, to the actual Ear Tube surgery and then post op appointment, they made it a stress free process. Also, they are very flexible and were able to get our appointments in, when we needed them! They definitely took care of my son and I am one happy Momma! ”

“This is how healthcare should work. Setting up the appointment was quick, easy, and even pleasant. I was welcomed by the staff and had just a short wait before proceeding to the exam room, where I waited a brief time for Dr. Maschka. When he arrived, he listened to my concerns and proceeded to an exam during which he shared what he was doing and why. He conveyed his findings clearly and suggested a path forward that was appropriately conservative (no need to rush to overly aggressive intervention). I cannot imagine a better experience.”

“Dr. Warren and his staff are caring and knowledgeable. I was recently seen for a bout of Vertigo. Dr Warren took his time to explain everything to me and commented that he did not want me to leave until I felt all of my questions had been answered 🙂 His staff knew how to maneuver me to stop the dizziness and educated me on what to do in regards of home care. I would highly recommend them!”

“I have chronic sinus problems due to recurring polyps. After my move to Denver, I began seeing Dr. Morrissey and he planned a treatment that was a game changer. My quality of life has improved so much for the better. I am breathing well and have no chronic cough. I highly recommend Dr. Morrissey.”

“This office is a well oiled machine. The first intial appointment the office staff was very friendly and efficient. Wonderful return calls from the PA Myria and Jensen. Dr. Warren was extremely thorough on my exam,took a lot of time with answering my questions. I feel very confident with his care. And I don’t want to forget the audiologist test……..this lady was outstanding. Best medical office visits I have had in years!!!!!! Wish all medical offices function like this.”
