Voted Charlotte's Best ENT/Otolaryngologist!

Standing in contrast to the growing trend of “Big Medicine,” where care can often feel impersonal, rushed, and disconnected, CornerStone Ear, Nose & Throat prioritizes care and long-term patient relationships while consistently delivering clinical excellence. CornerStone ENT was founded on the principles of clinical expertise and an unwavering commitment to each patient – which they have been honoring for over 31 years.

What makes the practice able to deliver such exceptional care are the people who work at the office. From the front office staff and medical assistants to the billing and administrative teams, every member plays a vital role in creating a positive experience for patients.

“At CornerStone ENT, patients aren’t just numbers in a system; they’re neighbors, families, and individuals we’re honored to care for,” said Dr. William McClelland, lead physician and founder of the practice.

As the founder, Dr. McClelland leads the practice with expertise and experience. He has a particular interest in minimally invasive nasal and sinus surgery designed to provide lasting relief from chronic conditions.

One patient said, “He was amazing. Took time to really listen to me. He was attuned to my feelings and recognized I was nervous. I would recommend him to anyone. Dr. McClelland is so skilled and supportive and the whole team at the office and the hospital was terrific too.”

For over 31 years, the practice has cared for more than 100,000 individuals – each with their own story, challenges, and goals. Being trusted with their care is an honor that is never taken for granted.

A patient had this to say about their experience: “Upon arrival I was met with a very bright, welcoming spirited office receptionist. As someone that has PTSD from dealing with countless physicians and administrators, it was a breath of fresh air to finally be handled with care.”

The team at CornerStone is made up of caring professionals who are passionate about making every patient feel welcomed and supported. With a team of board-certified ENT physicians and doctors of audiology, the practice provides both surgical and non-surgical options for ENT conditions – all under one roof.

Dr. Tyler Janz joined the practice in 2025 and is a dedicated otolaryngologist with a passion for providing exceptional, patient-centered care to individuals of all ages. With a thoughtful approach, he treats the full spectrum of ear, nose, and throat conditions.

A patient of his commented, “He came in and got straight to the point about everything I had concerns about and provided me with great care. I love my new doctor. If there were ten stars, he and his staff would definitely get them.”

Dr. Matthew Gillihan helps adults and children with all types of ear, nose, and throat disorders. For more than 20 years, Dr. Gillihan cared for patients in New Mexico before moving to Charlotte and joining the team.

“Very knowledgeable and caring doctor…very attentive to my questions with great bedside manner,” said one of his patients.

Karen Greene, PA-C is a physician assistant specializing in otolaryngology, working closely with the physicians to provide the highest level of care for children and adults suffering from ear, nose, and throat disorders.

One patient said, “I thought Karen was great. She has a bubbly personality and really seems to know her stuff. She’s very good at listening and explaining everything. She is an asset to have on your team - really enjoyed seeing her.”

Stephanie Griffin, AuD; Mary Darko, AuD; and Chasity Walton, AuD are expert Audiologists that play a vital role in the accurate diagnosis and treatment of hearing concerns for patients of all ages. Their goal is to listen to your concerns, provide accurate hearing and balance testing when needed, and offer the solution that best fits your lifestyle.

“We’ve added new team members and providers, expanded our services, adopted state-of-the-art technology, and introduced in-office procedures that make care more convenient and effective,” said Dr. McClelland.

With a specialization in nasal and sinus surgery and a mission of providing patients with the very best care, one thing that sets CornerStone ENT apart is that most of the nasal and sinus surgical services are provided in-office. This allows patients to receive high-quality care without going to the hospital, bringing patients the benefits of affordability, additional comfort, and ease.

One of the highest recognitions for the practice comes from within the medical community – Dr. William McClelland has been named a Castle Connolly and Charlotte Magazine Top Doctor multiple times, a peer-nominated distinction that reflects his clinical excellence and compassionate care.

“But the feedback that resonates most deeply with us comes directly from our patients,” said Dr. McClelland. “Whether it’s a life-changing improvement in breathing, hearing, or sleep – or simply feeling heard and cared for – those stories remind us why we do what we do.”
