Hi, I worked there for 3 years and can say it was a fantastic experience. They do a great deal of import/export and the credit card payment is done using the usual electronic method. If you have any concerns, you can always email the owner, he always replies quickly. [email protected] or speak to the manager Dr Khan. Also take a look at their Facebook page. They are one of several well established and popular clinics in Doha. They are always available to discuss anything.
