I am happy to recommend Katherin both as a medical writer and a voice artist.
She is self-driven, creative and intelligent with a can-do attitude which allows her to apply her skills to a wide range of situations and projects.
When recording scientific/medical content, it is a real asset to have a recording artist, like Katherin, who has a firm grasp of the content and hence does not need coaching on pronounciation of pharmacological terms.

I hired Katherin to assist me in all functions related to my editorial department. Katherin proved to be an efficient and reliable medical editor who helped me cope with an incredible workload. I soon realized that she possessed a wide variety of skills, way beyond the scope of an editorial position. She is a motivated, intelligent, and extremely competent individual who produces high-quality products on time. Her combined skill set would be an asset to any educational, research, or multimedia organization. I therefore strongly recommend her editorial and audio services.

Working with Katherin has been an absolute pleasure. She has a great work ethic, and has never been late for a deadline, in most cases returns the work we request well ahead of schedule, which is a huge asset for our company in meeting our own deadlines. Katherin has narrated for us in both French and Spanish, and her dictation and pronunciation in both of those languages has been outstanding.

We were looking for a professional narrator with a biomedical background who would be able to shape our weekly podcast based on our heartwire news service, understand and animate complicated concepts and work with difficult vocabularies. On top of an excellent voice, we wanted someone who would be able to understand the nature of our online cardiology services and be able to work independently with little management. Katherin has succeeded in all respects—she has now edited and narrated over thirty podcasts, setting exemplary standards of excellence and being a key factor in the success of our This week in cardiology podcast.

We use many voices and whilst this is the first time we have used Katherin, We found her voice over and translation services to be first class, with fast response to our emails and clear questions from her about the job to ensure that Katherin delivers exactly what you require.
We also found that her studio sound is of very high broadcast quality, delivery of her spoken voice recording was perfect and translation very good.
We will definitely be using her Greek voice again for many of our clients.
Thanks Katherin.

Katherin is fantastic. With just one round of feedback on a short script sample she was able to adjust and quickly deliver a perfect revision. Whenever we need VO work done in the future we will only use Katherin!

I would recommend Katherin to anyone who needs professional voice over work for any number of projects.
