He was directly to the point clear about diagnosis
Dr. Arjun Dhayalan, M.D., specializes in hand and upper extremity surgery, drawn to the field by the complexity of the anatomy and the problem-solving it requires. He believes that the hand, wrist, and elbow demand precision and thoughtful decision-making, noting that even small improvements can lead to meaningful changes in how patients function day-to-day. Orthopedics allows him to combine detailed anatomical knowledge with practical solutions that directly improve quality of life.
Dr. Dhayalan places a strong emphasis on non-operative care whenever appropriate, ensuring that surgery is only recommended when it truly offers the best outcome. When surgical treatment is needed, his clinical interests focus on minimally invasive techniques and office-based procedures using local-only anesthesia (WALANT).
“Patients can expect a thoughtful evaluation, an honest discussion of all available treatment options, and a care plan tailored to their goals, lifestyle, and comfort level.”
In 2016, Dr. Dhayalan was inducted into the Alpha Omega Alpha Medical Society. His research includes work on carpal tunnel syndrome and other hand conditions, with national presentations focused on improving diagnosis, surgical decision-making, and patient outcomes in hand and upper extremity care.
Outside of work, Dr. Dhayalan enjoys spending time with his wife, their two young daughters, and their mini Australian Shepherd. They enjoy cooking, outdoor activities, and spending time together as a family. He believes these moments help him stay grounded and guide the same thoughtful, attentive care he provides to his patients.
