When it comes to the world of high-end interior design, few names have captured the public’s attention quite like Jeffrey Alan Marks and Ross Cassidy. Known for their appearances on Bravo’s hit series Million Dollar Decorators, the duo quickly became fan favorites — not just for their impeccable design taste, but also for their charismatic on-screen chemistry and real-life romantic relationship. However, much to the surprise of fans, the two decided to part ways both professionally and personally.
The announcement of their split wasn’t a dramatic affair. In fact, it was marked by mutual respect and a continued collaboration. While some celebrity splits become tabloid fodder, Marks and Cassidy handled the situation with a notable level of grace, showing that love and friendship can still endure even when the romantic chapter comes to a close.

The Professional Partnership
Jeffrey Alan Marks established himself as one of the top names in interior design, with a distinct style blending classic elegance and coastal casual. With clients ranging from top Hollywood executives to global luxury brands, Marks’s reputation is built on excellence. Cassidy, younger and with a background in modeling and set design, brought a fresh and avant-garde perspective to the table.
Together, they created a dynamic creative force. Their designs were a visually stunning mix of old-world charm and modern minimalism. The pair complemented one another in a way that seemed almost choreographed: Marks providing the refined eye for tradition, and Cassidy injecting bursts of boldness, color, and geometry. Their work was frequently featured in high-profile magazines such as Elle Décor and Architectural Digest.
The Personal Journey
Their relationship, both personal and professional, was spotlighted on Million Dollar Decorators, giving fans a peek into their interactions beyond just room makeovers. What viewers saw was a couple navigating love and work in a high-stress, high-style environment — a rare blend of vulnerability and sophistication that made them all the more relatable and admired by viewers.
However, not all relationships are meant to last forever. Over time, they decided to part ways romantically. Rather than letting it affect their careers negatively, both designers took the opportunity to redefine their individual identities. In an interview, Marks commented on the split, saying that “relationships evolve,” and emphasized how thankful he was for the years they spent together.
What Led to the Split?
Although the pair never delved publicly into deeply personal details, sources close to them indicated that their professional pressures, diverging creative visions, and different life goals contributed to the decision. It wasn’t marked by scandal or conflict — rather, by personal growth and mutual respect.
The split was less about disagreement and more about evolution. As Cassidy began exploring new avenues, including television and product design, Marks focused on expanding his own brand with projects spread across the United States and Europe.
Where Are They Now?
Both designers have continued on upward trajectories in their respective careers:
- Jeffrey Alan Marks has launched successful furniture lines and remains one of the most sought-after interior designers in the industry.
- Ross Cassidy has branched out into design shows and has been involved in innovative product design ventures. He’s known for pushing boundaries and bringing a worldly, structured aesthetic into his work.

Though they no longer work together intimately, fans still remember their projects as a highlighted era in modern interior design. Their collaboration not only transformed spaces but also changed the conversation around same-sex couples in the high-end design industry. They helped normalize queer visibility in a professional setting without making it the center of attention, instead focusing on their undeniable talent and synergy.
The Legacy They Leave Behind
Though Jeffrey Alan Marks and Ross Cassidy have gone their separate ways, their contribution to interior design remains significant. Their time together symbolized not just creativity and innovation but also respect, understanding, and evolution. They remain friends and colleagues in the same competitive industry — a statement that speaks volumes about their integrity and professionalism.
Fans may have been disappointed to see their romantic chapter close, but there’s a sense of admiration for how they handled the change. Rather than dwelling on the end, both chose to celebrate a new beginning, paving the way for future creative ventures and personal growth.
In a field where style constantly evolves, so too do the relationships behind the scenes. And while Marks and Cassidy may no longer be a couple, their story continues to inspire — a tale of creativity, change, and dignity in the world of design.
