My initial visit with Dr Cohen was excellent. From the moment I arrived, the team was welcoming and efficient. The doctor took the time to listen carefully, explain everything clearly, and address all of my concerns without rushing. I left the appointment feeling informed, reassured, and confident about the plan moving forward. A genuinely positive experience.

Dr Cohen was so lovely and calming, he really made me feel understood and seen and took my concerns and needs seriously. I felt that he listened to be and also talked me through his thought process and the reason behind his assessment and subsequent referrals - this really put me at ease and made me feel taken care of and confident that we would get to the bottom of my diagnosis

Dr Cohen is always great, clear with treatment plans, takes time to see how I’m doing and get my view on treatment too. He’s approachable, professional but also light hearted and funny which makes seeing a doctor less daunting. Always happy to see him

Appointment was fine, General notes regarding the follow-up letter: At the beginning (No 8 under diagnosis) it shows a weight measurement which is significantly out of date. The letter shows 2 different height measurements. Surely they can't both be correct?
