About Us

C2G Design provides Interior Design and Space Planning services for commercial environments. The company was founded by Carmen Costinescu in 2004 in Columbus, Ohio.

Carmen received her formal education in Industrial Design at Ohio State University and earned a BS in Interior Design. She has worked and collaborated on projects for dental and health care industries, retail and hospitality. She keeps up to date with all the latest trends, research and products available through numerous seminars, courses and media presentations.

C2G specializes in Interior Design for the dental industry such as orthodontic, oral surgery, general dentistry, and pediatric dentistry. Many of our projects for both new built and remodeled environments can be found in Ohio as well as Kentucky, and Illinois. Our holistic approach brings together space planning, function, color, texture, and lighting to create the desired brand and environment experience, and we offer a unique combination of industry knowledge and experience combined with fresh thinking, creativity and cost effective implementation solutions.

We highly value our relationships with clients, architects and builders. You can rely on us as part of your team, from concept to completion. Many clients come to work with us to bring their vision to life and return for multiple projects or recommend us to their friends and peers. We consider that to be the ultimate compliment.

Carmen is the Interior Designer chosen by me to develop the modification and construction plans for a Surgery Center Office Space. My work with Carmen began about one year ago and I can say without reservation that the experience in working with her was absolutely fabulous. She has a keen attention to detail coupled with impeccable taste and the ability to work with any budget constraints. She developed a plan that was within the range of features desirable and adjusted the design features to achieve that high end look without the high end cost. The result was truly exceptional and projects exactly the image that my business needed to project to the patients. She has been extremely helpful and always reachable, even after-hours, if a design challenge developed during construction. She was always responsive and provided the correct and expected input to allow the project to continue on schedule. Anyone using her services can expect a perfection-driven attitude and a truly impressively beautiful and functional final product. Recommend without any reservations whatsoever!

Carmen was recommended to me when I was relocating my practice to a new location. I couldn’t have found a better designer. She was attentive to my taste in styles and skillfully wove a design that incorporated the key elements I wanted with unique touches that made the entire project a real “wow factor” to our patients. Everyone that comes to the office is amazed at how incredible it looks. Carmen did a fantastic job and I recommend her continually to professionals that I come in contact with that are looking for a trustworthy professional designer.

Carmen designed my office from scratch, starting from the floor plan to every single detail in the office. I’m extremely pleased with the outcome. Everyone that steps in my office comments on the beauty of the design. Not only did I get a great outcome. but I really enjoyed working with Carmen. She’s a great person & goes the extra mile. It was the best decision I ever made when starting my practice to have her on board & I definitely recommend her.

Carmen helped us out with two large projects that were both successful. I would highly recommend her services.

Drs. Mona and Tony Rinaldi

Owners of Rinaldi Orthodontics

Carmen helped with the design and build out of our two new orthodontic facilities. She was always a pleasure to work with and provided us with all the design information we needed to make the right decisions. Both of our new locations turned out beautifully and we are very pleased with results. There is a constant stream of compliments from our patients. I would not hesitate to use Carmen again for our next build out.

Dr. Scott Soderquist

Owner/Partner at Associated Orthodontists

Carmen helped me design my Dental office. I designed the floor plan but I needed help with the interior design and elevation. She was able to communicate my ideas and add to them to create the design that I envisioned for my new office. The final result was superb! Carmen is not an interior decorator. She is an actual commercial designer that understands architectural plans and can create plans including lighting plans which is very important. What she provides is the difference between creating a mediocre space and one that is fantastic! I enthusiastically recommend Carmen for your project.
