Marina worked on many of my personal and my husbands business projects We found her to be very knowledgeable, professional and cooperative throughout the course of each project. In addition, after completion of work, she has been responsive and thorough in addressing any minor issues associated with the project. I would recommend MG Interior Art and Marina Gorelova personally, without hesitation.

We met with Marina 10 years ago. We did repairs in our condo and invited Marina as a designer. The building was not an easy one, since our apartment is very small. Originally the goal was to visually expand the space. And Marina brilliantly coped with this task. As a result, not only we were delighted, but all our friends and relatives. Now we are thinking about updating our interior. We will only contact Marina. She is the best!

Marina made the design for our 2 bedroom apartment. She created the whole concept. She managed to understand very well my character and my needs, so the design perfectly fits me - my inner world. Many credits to the level of professionalism: every detail is thoroughly planned and perfectly done! She is both very talented and creative artist and a smart manager! I definitely recommend her as a designer if you want to get a place for living of your dream!

It was a great pleasure working with Marina. She is extremely skilled and talented. Our house became " alive" with her impeccable touches. She knew exactly what had to be done so it would not be " over the top". In addition, Marina is also very responsible and she finished the project in a very timely manner. She is also a perfectionist and she took time to triple check her work before completion. I would highly recommend Marina because she is skmply the best at what she does!!!
