In Dr Salahaddin Ubaid I had a medical genius who also contributed significantly to aiding me overcome all of the negative worries and emotions I was feeling. The care he provided to me, his attention to detail, his personal knowledge, expertise, experience and skills was outstanding.

Your kindness and good humour were very much appreciated and certainly put me at ease throughout the procedure, which on other ocassions has been quite daunting, your relaxed approach to my problem was very calm and professional.

What I valued as much as his erudition was his people skills, he related to everyone as an individual, his understanding, communications, interactions and personable nature were exceptional. Dr Ubaid was quite simply staggering, he is somebody that has had a significant impact on me, not just for giving me my life back and for his medical genius but for being the person that he is.

His presence radiates a warmth, he instils confidence in all those around him, he sets an example for others to follow and is a role model for others to aspire to be like. He was kind, courteous, professional, understanding, caring and highly approachable and relatable as well as the medical guru we all benefit from and rely on to give us our lives back.

Dr Ubaid works well with all the staff. His approach to his fellow workers is both patient and respectful. His easy going manner makes him very approachable to ask advice and he accommodates any delays graciously. I personally look forward to working with him.

A great team player, all of the nursing staff are very happy to work with Salahaddin as he is polite, efficient, and has a great aura of calmness and competence and appreciates the time to be light-hearted.

In life we all need role models, if I was in training to be a doctor you would certainly fit that role for me. I thank you so much for what you have done to allow me to continue with my fitness regime and wish you well in the life ahead of you.
