Patients' Feedback

  • This was my second consultation with Mr Ellis at One Ashford regarding a recurring knee problem. I have always found him to be very pleasant and extremely helpful. He takes the time to listen to you and explains the problem and any treatment in great detail. I would have no hesitation in recommending him.
  • Mr Ellis provided excellent care for me during my recent issues with my knee. He was always approachable and explained my care thoroughly. He phoned my family straight after my recent operation to let them know how it had gone which I thought was an excellent level of care. I know that I will need more intervention with my knee in the future and hope that Mr Ellis will be able to provide this.
