Lisa and Tiffany

MANSFIELD + O’NEIL is a vibrant and creative design collaboration, fashioned from two distinct but complementary points of view. As a team, we are committed to excellent design, strong relationships, and professional project execution.

We bring the spirit of a home to life by honoring and enhancing the unique nature of its space:

    • our vision is eclectic, contemporary, dynamic, and integrated
    • we design for the way people want to live: family-friendly, approachable, comfortable
    • we favor sophisticated and subtle use of color; we aren’t afraid of bold hues but also embrace tranquil, textural palettes
    • we work collaboratively and communicate transparently with our clients to deliver in their best interests
    • our body of work speaks to our passion and range of talent, while reflecting a pragmatic understanding of budgets and other concerns

Tiffany Mansfield is intuitive and chic, connecting deeply with clients to create dynamic design solutions. She’s classically trained in art and design and is uniquely independent and imaginative. She offers 15 years of expert design practice and business management experience.

Lisa O’Neil is smart and stylish, interested in people and how they live. She’s committed to the perfect balance between beauty and function. Her acumen is grounded in a top-tier liberal arts degree and MBA. She offers artistic and project management skills honed from 10+ years of design practice and a prior career as a corporate executive.
