Client Quotes

“I wish to compliment Vassilios on his outstanding architectural performance, while providing professional services to Advocate Health Care. Project after project, Vassilios has delivered quality services to his Advocate Customers and we appreciate it. One of the characteristics that separate Vassilios from his competition is his ability to position himself as a member of the Advocate team, as a member of the Advocate Family – if you will. He is ever available by cell phone and responds within 24 hours reliability to our requirements, questions and issues. I have worked with scores of architects during my 22 year career and find Vassilios’ professional expertise (in clinical and other Laboratory design and operations) and Professionalism to be truly excellent. He is preeminent architect. Yes – the ACL Lab people love Vassilios. They refused to work with anyone else. That old school work ethic has really paid. Thanks again Vassilios.”

“Hi Vassilios,

Just wanted to send you a BIG THANKS. We moved into our new offices this week and we couldn’t be more pleased. Everything turned out very well; even the carpeting which I had many misgivings about before it was installed matches well and looks great. The extra space we have and the layout you designed are like a big breath of fresh air for all of us. It makes a huge difference to have such a pleasant place to work.”

“We have worked with Vassilios Nicolaou on multiple laboratory design/construction projects over the last 10 years from new lab space to renovation of existing space.  These labs range from basic hospital core Laboratories to a large 80,000 sq. ft. Reference Laboratory which included Core Lab, microbiology, Histology, Cytology, Cytogenetics, Molecular, and BSL3 TB Lab. Vassilios is extremely knowledgeable in the principles of LEAN as related to laboratory design. The Good Samaritan Hospital laboratory has become a showcase. We have many requests for visiting our site.   It is always a pleasure to have a new project, with anticipation of working with Vassilios.

“In ACL’s Reference Laboratory in Rosemont, Illinois we recently added 9,000 sq. ft. to its existing lab space. 5,500 sq. ft. Cytogenetics Laboratory, 500 sq. Microarray lab, 2,000 sq. ft. Pathology offices and 500 sq. ft. state-of-the-art Conference Room designed by Vassilios Nicolaou in conjunction with the lab staff.  Vassilios’ one-on-one meetings with key lab individuals were critical to the success of the project.  His attention to detail and the infusion of art with science produced an artistically appealing, modern, and efficient laboratory”.

“I commend Vassilios Nicolaou with whom I have worked for over a year to design the research laboratory for the Dr. John Macdonald Foundation Center for Medical Genetics. He demonstrated a high level service, commitment and design expertise during the execution of this project on the sixth floor of the Batchelor Children’s Research Institute. It was my pleasure to work with Vassilios, and I greatly appreciated his responsiveness and attention, His philosophy to include my research colleagues during the design process was greatly appreciated”

“Dear Mr. Nicolaou: We have been in our facility for about two months and I wanted to take the time to write you and tell you how much we appreciated your sensitivity and devotion to our needs. As you are acutely aware, it is important, that clinical environments be pleasing to the eye as well convenient for our patients. Without your tireless efforts, we could not have planned such a beautiful mental healthcare. Your willingness to meet with us at “the drop of the hat” and promptly return our telephone calls, was particularly impressive especially in light of all the questions, concerns and uncertainties of a renovation project like the Byrd Building.”

“The floor is truly fabulous, much better than I envisioned, and I designed it … least in an overview way, Vassilios was the guy who took care of the reality. He is great. The quality is far better than our labs at Tufts.”
