We have been working with Raylytic for more than a year now, building a database for 2 retrospective studies and running quantitative and qualitative measurements analysis for the uploaded radiographic images needed for the same studies. As the CDM of the project I have been working very closely with Mariana, Marcel and Frank.The whole team has not only shown excellence in the whole aspect of helping designing the eCRF, implementing and training how to navigate the database, providing the necessary documents, fixing any issues that we might have but went above and beyond on helping us achieve our short and long time goals. Working with Raylytic is honestly fantastic, not only they showed a high excellence professionalism, highly knowledgeable on how to run clinical retrospective studies but also the flexibility and the patience to help in anyway they could to achieve our targets. I would highly recommend them for any projects you might have, and enjoy working with them. A special Thanks also to Mariana who I have been closely working with on a daily basis. she is not only highly intelligent and hard worker but has shown a constant support and will go above and beyond to achieve your present and future goals. Will highly recommend Raylytic anytime.
