What Patients are Saying

Always kind and patient. Understanding and solves problems. Deeply appreciated
Dr. Costas reviewed me in clinic, really listened to my story, and explained everything in a very simple manner. He put me at ease before the colonoscopy, which was performed very smoothly and painlessly. I would highly recommend!
I saw Costas in clinic after having symptoms for a number of years. I immediately felt heard. We decided on a treatment plan together and I can finally see a way forward. Thank you Dr. Parisinos!
I visited Dr. Parisinos for a chronic undiagnosed problem that I hadn't been able to get help on from other doctors. He was incredibly thorough with the examination and the tests he requested and I finally have a diagnosis and a management plan I can follow. Dr. Parisinos is also very kind and caring and that's has been very reassuring especially when dealing with a chronic issue. I would highly recommend him!
The treatment I received today from the doctor was excellent, my diagnosis was explain very clearly to me and the treatment going forward was explained in such away that I could see light at the end of the tunnel, the condition I have could be life long, but hopefully with the correct medication I will be cured. So overall my consultation was very professional, prompt and a relief to me. Thank you so much.
I was very worried today to have an endoscopy performed under sedation. Dr Parisinos explained everything, kept me very calm, and performed a skilled procedure to manage my condition in a matter of minutes. The whole experience was exceptionally efficient and the endoscopy effortless and very smooth.
I want to sincerely thank you for the exceptional care and attention you provided during my last appointment. You truly took the time to listen to everything I was saying, and I felt genuinely heard and understood. Your thoughtful approach, clear communication, and willingness to explore solutions made all the difference. Because of your efforts, I was finally found in the system, which led to me receiving my much-needed stomach surgery — and with one of the best professors, no less. I am incredibly grateful for your support and professionalism. You went above and beyond, and I couldn’t be more thankful. We are lucky to have a specialist like Dr. Parisinos. Thank you!
I recently had an appointment with Dr Parisinos, and I was impressed with the care I received. He was thorough in his assessment, listened attentively to my concerns, and explained everything in a clear and reassuring manner. I felt genuinely cared for throughout the consultation. He prescribed the appropriate medication and arranged further investigations to ensure nothing is overlooked. I left feeling confident that I am in very capable hands. Highly recommended.
Professional friendly service. Took his time to explain everything thoroughly.
The doctor was very calm and gentle with my autistic son. He was knowledgeable and kind which really helped.
