Architects & Staff

Amber Roth, R.A.

Architect, NCARB

Amber joined AVGA in early 2005 when she moved back to Long Island after working in Arizona. She received her Bachelor of Architecture from Syracuse University and in 2005, she obtained her Architectural License from the State of New York.  Amber worked in Manhattan and abroad for a number of years gaining experience in retail, senior housing, corporate interiors and classical architecture before pursuing her passion for residential architecture, both traditional and modern.  While at AVGA, Amber has enjoyed working on many amazing projects as well as the friendships she has built among this small, close-knit group of professionals.

Andrew L. Giambertone

As the youngest member of the firm, Andrew originally came to Giambertone Architects to help out around the office with day to day tasks, intending to return to school. After a few weeks however, he had taught himself how to create 3D models of the firm’s projects and create photorealistic renderings which allow clients to see what their homes will look like before the first brick is laid. He has since fallen in love with 3D design and architectural visualization, as perhaps his father expected, and has taken his place in the office as a 3D Render Artist. He is excited to continue to grow with the firm and bring their designs to life.

Bujare Kollqaku

Bujare is a licensed "Engineer of Architecture" in (former) Yugoslavia, where she graduated in Prishtina University. Additionally, Bujare pursued a masters degree at the Zagreb University- Croatia, however she was unable to see it to completion as a result of political turmoil. Bujare worked in Architectural and Urbanism Faculty in Prishtina as a professor while working in an architectural firm in Prishtina. After moving to the United States, Bujare spent time working in an architecture firm in New York before she joined us at AVGA.

                 "Giambertone’s architecture is where the classical architecture, with all of its elements, enriches surroundings where those values still hold true. With amazing fine-tuning and incredible attention to detail, our work enlightens the most elegant and thoughtful contemporary side of architecture - that's where I found my passion. Having taught and practiced architecture for decades, I'm honored to be part of a team that incorporates such thoughtful design."

Dennis Radzinsky

Dennis Radzinsky has worked at Giambertone Architects for 20 years.  As a young boy he was immersed in the field working alongside his late father.  This inspired his passion for architecture in which he received his Bachelor of Architecture from New York Institute of Technology.  Dennis is always working under the premise that you need to create an optimal set of detailed drawings and he applies his broad experience both in architecture and construction across all projects.  He holds himself to high standards and exhibits cohesive leadership within the company.

          “As a Project Architect, I have the pleasure to work with a diverse group of talented colleagues.  Together we collaborate on intricate details on luxurious homes.  Giambertone Architects merges clients wishes with unique elements to make one of a kind homes”.

Ernesto Silva

Ernesto Silva has 20 years of  professional experience in the Architectural field, 12 of which have been with Andrew V. Giambertone & Associates.  Ernesto has been responsible for overseeing, composing design development and construction documents for both exterior and interior phases of some of our projects.  Based on our firm’s attention to detail and implementation of that detail throughout the construction process, Ernesto works closely with the Construction Manager and individual trades in the field, through site visits and meetings, to ensure the final built product is consistent with the initial design intent.  Ernesto holds a Bachelor of Architecture from New York Institute of Technology.

             There are several aspects of our firm which makes my experience here unique and fulfilling.  First,  is the quality of projects we get to work on and the fact that for most projects we have the opportunity to stay with the projects from start to finish, therefore providing us the opportunity to experience all aspects of the project, which is extremely valuable for our professional growth and experience. Second is the level of detail and attention we give to all our projects. Third is our office environment which is unlike any other I have experienced, the level of competence amongst all my colleagues is exceptional with the combination of us all contributing towards the great family environment we have.  Al these make for a unique and fulfilling environment to work in.
