Diana Leiner is the founder of Toile & Oak Interiors, where thoughtful design, functionality, and personal style converge to transform spaces into true reflections of clients' unique visions.

Diana’s love for interior design has been a part of her for as long as she can remember. From a young age, she was captivated by the art of creating beautiful, functional spaces that tell a story. This passion naturally grew into a career dedicated to helping others achieve their dream environments.

Based in the Lehigh Valley, Pennsylvania, Diana primarily serves the Lehigh Valley, Greater Philadelphia area, and Central New Jersey, but her design expertise extends nationwide, working with clients all across the U.S.

Her journey into the world of design has been fueled by her desire to create spaces that blend beauty with functionality and tell a beautiful story. Diana’s portfolio began to grow as she designed homes for friends and family, her unique approach gained attention and enabled her to quickly grow her client base.

In 2024, Diana and her husband became Airbnb hosts. Designing their first rental property was a transformative experience, one that led to the birth of Toile & Oak STR Design—a division dedicated to creating stunning, profitable short-term rental spaces.

Today, Diana’s mission remains clear: to help homeowners create the homes they've always dreamed of—spaces that are a perfect balance of style, comfort, and functionality. Additionally, through Toile & Oak STR Design, she helps short-term rental hosts craft spaces that not only attract guests but also maximize profitability through design strategies tailored to the market’s needs.

Whether designing a personal sanctuary or transforming a short-term rental into a standout destination, Diana is passionate about collaborating with clients to bring their visions to life and create beautiful spaces.
