Dr Allen listened to all my concerns and worked with me in finding the best steps to take next.
Great Doc!
I am very pleased with my experience as a patient of Dr Allen. I had an issue with me knee, was able to see him fairly quickly, and start a treatment program. Very knowledgeable and explains in details the pros and cons of the various treatments options so I can make a decision on what’s best for me. Very appreciative of the care I am receiving as a new patient.
He was Awesome. He explained my options we made a plan for my care. So happy to have some relief from pain.
Highly recommend
Quick and thorough
Dr Allen was courteous, thorough and professional. He was on time and walked us through the X-rays. We made a decision on treatment and we were very happy with the outcome of the appointment.
Easy to talk with and very informative!
I was sitting so he sat to put us on the same level. He had obviously reviewed my chart. He asked pertinent questions and discussed with what my options were and accepted my decision to see if the steroid would work better the second. He answered all of my questions and was quite pleasant. I feel that I can trust him.
Attention to detail
