Beautiful compassion for my dementia patient. Great waiting room.
Thank you
Professional, yet friendly. Listens to me when I'm describing issues I'm having. Patient and kind. My Mom had several hip replacements, all ill-fitted until Dr. Mullen operated on her - no problems in many, many years. I trust Dr. Mullen and his opinion 100%.
Good communication, friendly, informative, spent time with me.
Wise, friendly, kind and thoughtful.
Cortisone injection was painless! Also made plan for knee replacement with Dr Muller. I am an experienced patient with both major and minor surgery and Dr Muller’s info on the procedure gave me confidence and reduced my concern for aspects of it.
always a great visit
Exceptional Doctor! He's the real deal.
Outstanding doctor!
I’ve known Dr Mullen for many years. He’s the most caring doctor, very thorough and an excellent surgeon.
