About Us

Our Practice

Montgomery County ENT Institute was founded by Dr. Melissa Schwartz in 2007. After ten years of experience in other Ear, Nose and Throat practices, Dr. Schwartz saw the need to start a practice which concentrated on personalized and specialized care for her patients. Montgomery County ENT Institute later merged with Dr. Sondra Saull’s office located in the Holy Redeemer Medical Office Building in Meadowbrook, PA, offering patients comprehensive care through an additional office location. Most recently, the practice has welcomed Dr. Hilary Sales to the group.

We have a particular interest in treating patients with chronic nasal and sinus complaints. We aim to incorporate our knowledge and expertise in allergy management to provide maximal improvement in the quality of life of our patients. The practice provides full service allergy management which includes skin testing and immunotherapy This includes allergy shots and sublingual treatment, more commonly known as allergy drops.

Our Audiology department includes three audiologists who offer comprehensive testing using state of the art equipment for management of hearing disorders. Hearing aid dispensing is done as well with the utmost quality aiming for 100% satisfaction from our patients.
