Deirdre Monahan is a board-certified physician assistant who has been caring for patients since 2009. She earned her degree from Nova Southeastern University in Fort Lauderdale, Florida, and spent much of her career in emergency medicine in Putnam. She also has experience in Naples, Florida and Worcester, Massachusetts.

Through her years in the ER, Deirdre treated a wide range of ear, nose and throat conditions—from sinus infections and earaches to dizziness and throat disorders—which sparked a lasting passion for the specialty. Today, she is dedicated to helping patients of all ages feel better, breathe easier and enjoy healthier lives.

A proud mom, Deirdre especially enjoys caring for children and helping families feel at ease during visits. Outside of work, she loves spending time at the beach in the summer, skiing in the winter, exploring interior design projects, exercising with her husband and pursuing natural and holistic approaches to health and wellness for herself and her family.

Sara Witek is a clinical audiologist who finds great meaning in the moments when patients rediscover sounds they had forgotten existed. Whether it’s the subtle background noise of daily life or the voices of loved ones in a crowded room, she is driven by helping individuals regain confidence and independence through better hearing.

Dr. Witek earned her Doctor of Audiology from Arizona State University and her Bachelor of Arts in Communication Sciences and Disorders from Saint Xavier University. With six years of experience in diverse clinical settings, she has developed expertise in pediatric audiology, adult cochlear implants and hearing aid care.

Sara played a key role in expanding access to advanced hearing treatment by creating and launching an adult cochlear implant program at Munson Medical Center in Traverse City, Michigan. She has also been deeply involved in clinical education—precepting doctoral students throughout her career and training new clinical staff in diagnostic evaluations and hearing aid care at Massachusetts Eye and Ear. Her background reflects both strong clinical skills and a commitment to mentorship and program development.

Her approach to care is grounded in collaboration, careful listening and clear communication. She believes treatment plans should fit the whole person in real life—not just the audiogram—and values working alongside patients to ensure they feel informed, empowered and supported throughout their hearing journey. Few moments are more rewarding to her than witnessing the transformation cochlear implant recipients experience as they regain independence and reconnect with their world.

Originally from Chicago, Sara now lives near Boston, Massachusetts. Outside of the clinic, she enjoys reading fiction, traveling to explore new cities and taking on creative DIY projects—recently discovering a love for stained glass art after completing her first piece.
