About Us



By the time Michael Manheim graduated from Verde Valley school in Sedona, Arizona he had lived in eight different houses, studied architectural drafting, built a Navajo hogan, spent time with Paolo Soleri and met Frank Lloyd Wright. Though Mr. Manheim’s early fantasies of becoming an architect were crushed by the realization that he couldn’t draw to save his life, in 1986 he began designing and building homes for his personal use, leading to the creation of the real estate development company, Jaman Properties in 2003. To date, Mr. Manheim has redesigned or built more than twenty high-end residential properties.

In addition to his work in real estate, Mr. Manheim has played trumpet at Carnegie Hall, graduated with honors from Harvard university, produced 15 motion pictures that have earned 35 international awards including a Golden Globe and an Emmy, produced a Broadway musical nominated for a Tony Award for “Best Musical”, served on the Board of Governors of the Producers Guild of America and acted as an unpaid apprentice chef at two of the top Italian restaurants in Southern California. He resides in Malibu with his wife and creative partner of over 30 years, Janus Cercone.



Janus Cercone grew up in Bronxville, New York where her mother was a successful developer of high-end residential properties. Learning early what makes a house a compelling home, Ms. Cercone applies her skills as a screenwriter to designing unique spaces that reflect character and narrative. As such she is passionate in her belief in the transformative power of personal space. To date, she has built or redesigned more than 20 residences. Ms. Cercone attended Skidmore College on a full music scholarship, served as East Coast Director of Publicity for A&M Records – where she toured with bands who re-designed a few hotel rooms themselves, then worked as a songwriter and studio musician, contributing to numerous albums, award winning television and movies, before becoming a screenwriter and playwright. She has written 15 studio assignments for stars ranging from Michael Douglas to Johnny Depp. With composer Alan Menken, Ms. Cercone adapted her Steve Martin movie, “Leap of Faith” as a Broadway musical which received the Tony Award nomination for “Best Musical” and multiple Drama Desk nominations including, “Best Book For A Musical” for Ms. Cercone.
