INTEGRITY | QUALITY | LUXURY
Transformed Interiors was established by Diana in 2009 with the belief that our homes should be our happy places.
DIANA WERTHMANN
OWNER, PRINCIPAL DESIGNER
Design is not just what I do — it is an integral part of who I am. With over 25 years of experience in interior design, I bring a thoughtful, intuitive approach to creating homes that feel both beautiful and deeply personal. I see potential in every space and believe great design should support how you live, feel, and gather every day.
My clients often share that they value my strong sense of color, product knowledge, and my ability to truly listen. I am known for offering an honest, collaborative design process — one that balances inspiration with clarity, creativity with intention, and vision with practicality. My goal is always to understand my clients’ lifestyle and translate it into spaces that feel timeless, livable and like home.
One of my unique strengths as a designer is my love of numbers and problem-solving. This allows me to thoughtfully manage design investments, guide decision-making with confidence, and ensure clients get the greatest impact, comfort, and value from their homes — without sacrificing beauty.
As an active member of the design community and past president of our local ASID chapter and current Director of Finance, I am committed to continual growth and learning. I stay closely connected to emerging trends, materials, and products while remaining grounded in classic design principles that stand the test of time.
At the heart of my work is a deep appreciation for the relationships I build with my clients and the trust they place in me. Creating homes that feel welcoming, inspiring, and truly lived in is my greatest joy — and the reason I continue to love what I do every single day.
Kathryn Lipsitz
Interior Stylist
I am an artist and an interior stylist who is skilled in creating unique spaces that are both functional and visually striking. My art practice incorporates multimedia and 3D design, which I use to add depth to my work. I bring the same attention to detail and innovative approach to my interior design projects, using unique color and shape combinations to create indoor spaces that are both livable and beautiful. My ultimate goal is to create spaces that feel comfortable, where people and relax and feel truly at home.
