Outstanding!! Dealing with Dr. Cristaldi has been dealing with a Human before anything else. He immediately accepted to treat me whereas 4 doctors had refused to do anything to improve my condition after suffering for over 1.5 month and at least 3 unsuccessful surgeries and therefore lost the ability to perform some basic life needs. Dr. Cristaldi was extremely clear and honest about the steps forward. It took just one quick surgery and less than 2 weeks to get me back to work and retrieve a close to normal life. Six months later I was ready for another surgery to get me back to a normal condition.
In addition to be a great person to deal with, Dr. Cristaldi’s professionalism and extremely high-level expertise was also very impressive. His confidence level was transmitted to me and gave me the strength I needed to surpass this tough period. Privacy was also by far the best I’ve seen.

My experience with Dr. Cristaldi, his assistant Mrs. Hannah and the entire team at Harley Clinic was straight forward and I’ve never felt I was treated as a number while dealing with HSMC. I also never felt it was a business relationship. Indeed, I never felt at least one minimal push to get as much money as possible out of my condition. I’ve never been requested to do a non-necessary medical service/test etc.

With the combination of high-level expertise and a series of tests through state-of-the-art equipment the diagnosis was fast and very clear and therefore critical in the recovery process.

I would like to express my sincere gratitude to Dr. Cristaldi and his team… I will never thank you enough!

I had a severe pain at my rectum, pelvic area for a long time. I was glancing at internet if I could find a medication for this. Thanks to Allah, I found Harley Clinic and met Dr. Francesco, Giovanni, and Massimo who diagnosed and identified my problem.

​After two sessions of pudendal nerve treatment and thanks to Dr. Francesco and Giovanni who really carried both procedures in a professional manner, the pain disappeared.

I would like to thank all the Drs above and Claire who made me comfortable at the clinic.
Well done and keep up to good work.

– Mr. Saad Al
