Dr. Cara is a distinguished audiologist, as well as an adjunct professor and clinical instructor at Calvin University, dedicated to comprehensive ear and hearing care for patients of all ages. She completed her undergraduate and graduate studies at Western Michigan University in 1996 and 1998, followed by her doctoral work at AT Still University in Mesa, Arizona. With experience in varied settings—from the Veteran’s Administration and ENT offices to schools, hospitals, and specialized private practices—Dr. Cara has developed a diagnostic and therapeutic approach that emphasizes identifying root causes of auditory dysfunction and implementing effective, individualized treatments.


For both adults and children, Dr. Cara is committed to uncovering underlying issues affecting hearing and auditory processing, recognizing that accurate diagnostics are the foundation of effective care. She draws on Erber’s framework (1984) to create a solid structure for assessing auditory processing, brain health, and language skills, ensuring that each patient receives the insights and support they need to thrive. Her dedication to identifying core auditory and language issues empowers her patients to build essential communication skills and enhance their quality of life.


In pediatrics, Dr. Cara is a passionate advocate for early intervention, focusing on preventing language deprivation and supporting structured literacy and auditory processing skills essential for lifelong learning and communication. She believes that every child should have access to a strong language foundation, and she works diligently to provide diagnostic clarity and targeted therapies that address their unique developmental needs.


For adults, Dr. Cara’s approach addresses the complex interactions between brain health, auditory processing, and hearing ability. She prioritizes evidence-based diagnostics to uncover root dysfunctions, followed by tailored therapeutic plans that address each patient's specific auditory challenges. Dr. Cara’s commitment to combining advanced diagnostic tools with compassionate, personalized care has earned her a reputation for helping adults achieve meaningful, lasting improvements in hearing and communication.


Whether working with children or adults, Dr. Cara’s approach is holistic, empathetic, and grounded in her commitment to best practices. Her expertise in diagnostics and treatment allows her to provide patients of all ages with the tools they need to overcome auditory challenges and build stronger, clearer connections with the world around them.
