Heidi CCCMA(Medical Assistant), Mary (clinic nurse), HOME HEALTH CARE --- RizzaThe care that I received pre-surgery, on surgery day, and post-surgery was of excellent quality.

Maryann I am pretty sure is her name.Mary Ann or Maryloou said she remembered me and she made it easier to be myself. I really really really liked her.
November 09, 2021
Really, everyone with Dr. Cowley's office. The care I got from Heidi, his Medical Assistant, to the folks for PT, and ultimately Dr. Cowley himself. Granted the COVID pandemic created a few delays (2 months) but this doctor and his staff performed my surgery and follow-up care to perfection. They all listened and addressed my concerns. Felt completely comfortable with them and would recommend them to anyone that needs orthopedic care/surgery for their hips or knees. I am only 4 weeks out of surgery and I believe everything has been a great success.

September 16, 2021
Patient care provided by Heidi, Derrick and Dr. Cowley during pre and post operative visits was excellent.
September 15, 2021
Everyone has been excellent!
September 12, 2021
Dr Cowley and his MA are simply the best!Considering the fact I broke my hip, shoulder, and back all at the same time, and was your basic hot mess, (like Humpty Dumpty that fell off the wall) Dr Cowley put me back together pretty darn good! Especially since I'm no spring chicken anymore
September 10, 2021
Dr Cowley is the most informative Dr and so very helpful. Heidi is great and the other assistant, sorry I can't remember her name, are so very wonderful, friendly and caring. Everyone I dealt with was so helpful and seemed happy. I could see smiles in their eyes even behind masks! So unusual.

X-rays technicians
September 08, 2021
Daniel Cowley and his team Heidi [ ] and Mary - the MA's are always prompt, highly efficient and well versed in what needs to happen. I have full faith & confidence that my care is in good hands. I recommend Dr. Cowley to everyone that needs knee and/or hip orthopedic services. He is a stellar surgeon. Debbie and Ivy at the front desk are always friendly and willing to help in any manner necessary.
August 27, 2021
My situtation does not call for any immediate action. Everyone was very nice and professional. I was very happy with the way I was treated by everyone and wll return to see Dr. Cowley in the future when action is called for.
August 27, 2021
Dr Crowley relieved my chronic pain I had for over two years with a cortisone shot exactly where it was needed without any pain. Now I am pain free!
August 27, 2021
While the staff and medical assistant were responsive to inquiries, they weren't particularly proactive. However, that being said, this is probably a reflection of Dr. Cowley's shortcomings. For example, he ordered up blood work for me. I got the results back within 24 hours and the data had highlighted levels above the normal range. This raised a host of questions and concerns for me. No one from Dr. Cowley's office followed up for a week. In fact, I had to make an inquiry to find out what the results meant.
August 27, 2021
Everyone at Asante was amazing. from receptionist to Dr. Cowley's staff the care was exceptional. They changed my life.

July 28, 2021
I felt respected by and cared about by Dr. [NAME] and his staff. Which is not always accomplished for someone of my size. Dr. Kelly has never made me feel negative in anyway because I am a larger person. I feel like I get the same care and respect to give to everyone. And it is greatly appreciated.

Dr. Cowley and staff were all excellent
June 12, 2021
I was worried about the left hip replacement and honesty a little bit vain about depending on the walker to get around. The office staff calling me a "rock star" and a "triathlete" at the check ups really built up my confidence, in a kind and humorous way!
June 11, 2021
Dr Cowley, his care, and his team took great care of my concerns.Heidi, who took all our questions, scheduling, and updating my prescriptions did everything with friendly efficiency.

March 29, 2021
Where do I start.... Dr. Cowley, Heidi, and the entire staff were beyond any expectations that I had. My experience with the staff and Dr. Cowley was so relaxed and efficient. After my 1st consultation with Dr. Cowley I was sent downstairs to have my blood work, EKG, chest x-ray and to give a urine sample and that went as smoothly as glass on a table. 2 days later I was scheduled for surgery. It was a great experience from start to finish, THANK YOU EVERYONE

I heard from a friend that he was the best.When I meet him i understood what my friend was saying.He first had me tell him what was my problem because i had been seen by a few doctors before him.He then did a few motion tests, then off to x-ray and back to him for review.He explained the x-ray and why i needed a total hip. He was very, very nice and polite. I will come back tohim again and tell everyone to go to him for Orthopedic Surgery. Love you Doc.
