GP bounced me into Oaks because I am 80 and the NHS clearly has no interest in me. Dr. McStay was a breath of fresh and listened. No clear diagnosis but a number of possibilities. Very logical and professional approach.
Dr McStay was clear, helpful and patient. I was able to ask her about my concerns and she dealt with everything very quickly and professionally. What a shame the nhs can’t provide such good service.
