What Our Patients Say

Life is so much better. To wake up refreshed and feel human again is unbelievable. I actually dream now because I'm finally getting deep sleep.
John, Brighton
Immediately when I woke up from the surgery I felt like I had HD breathing. I could take breaths with much more ease. I felt like there was so much more air coming through my throat.
DP, Saline
Best thing I ever did; my husband says I am not snoring. I am no longer using CPAP, and I am sleeping 8 hours without waking up. Best of all, when I wake up, I feel rested.
NS, NoviCEO
MOSA Staff (Receptionist and PA) were efficient & courteous.

Dr. Akervall is professional, explains things in an easy to understand manner and takes his time with you. He has been my doctor for 11 years after treating me for tonsil cancer. I drive an hour each way for my visits because I wouldn't choose any other ENT. He is THE best!!
CW
Dr. Ho came in to see me at my visit with the PA. It saved me a trip from coming back - also, saved me time. He confirmed that I'm a candidate for septoplasty. Great news as I'll be able to breathe better soon! Dr. Ho was very nice and accommodating.

The PA was amazing. She was very helpful in explaining what was going on with me and very kind.

I got answers to my questions that I've had for a long time!
CK
From the time we entered the office, the secretary was kind and took time listening to me. The Doctor's nurse Becky welcomed us like old friends. The Doctor was fantastic and so gental even though he had to inject 3x. PTL for this place.
Theresa D.
Of all the professionals I've seen over the years for my throat clearing problem, Ellie is my favorite. First and foremost, she is a great listener and great communicator. She creates a comfortable, relaxed environment for our sessions, and, all of this is backed up by a wealth of knowledge.
Tom S
They always WOW me. Dr. Montero-Brandt is the best. I have not been sick once since my surgery. She still cares enough to see me every 6 months. I recommend her and staff for any ENT issues. I used to carry a pack of Kleenex with me all the time. Now I barely use them. I use to wake up stuffy every morning. Thank the Lord for directing me to MOSA.
Suzanne C
Both the receptionist (Erin) and check out person (Laurie) were very personable. The receptionist greeted us quickly & kindly. The checkout person helped us find a restroom to empty an ostomy pouch. The tech (Becky) wowed us too!
