  • Dr Parisinos is an excellent doctor who took the time to explain my liver condition in real detail and answered all my questions clearly. I felt well-informed and reassured throughout, and the advice I received was practical and thorough. Communication was outstanding — very responsive and easy to reach. I’m extremely grateful for the level of care and attention.

  • I recently saw Dr Parisinos at OneWelbeck and had a very positive experience. He was reassuring, polite, and genuinely friendly, which immediately put me at ease. He listened carefully to my concerns and took my symptoms seriously, ordering an MRI to address my initial reason for visiting. He also paid close attention to my IBS and showed real interest in helping me manage it, taking the time to point me towards helpful resources and practical steps I could take. I would highly recommend him.
