My mom is a patient of Dr. McClellan, and he is an amazing doctor. My mom needed emergency surgery on her hip, and he stepped in and did a wonderful job. He spoke with my brother and me after the surgery and answered all our questions thoroughly. He is professional and knowledgeable but also extremely personable. He cares about his patients and is an extremely skilled doctor. I would encourage everyone who needs an orthopedist to definitely call his office! He is the best!! And no... I am not related to him! I am just being honest!

Dr. McClellan and his staff are excellent to work with. They informed me in great detail as to the procedures, pre, during, & post procedure. He, himself was available to answer questions even on the weekends. I recommend Dr. McClellan to my family, friends, & colleagues often.
