Isabel Marques
Senior Vice President / Founder
Isabel has over twenty years of combined experience successfully placing household staff in fine homes across the nation and working in private homes providing Estate Management and Personal Assistant services to high net worth families.
Building long-lasting relationships with her clients is top priority for Isabel. She has successfully placed domestic household staff in some of the nations’ most prominent homes including many clients in the Forbes 400. Having experience on both sides of the industry, her understanding of client needs, and candidate experience results in finding long-term, compatible staff placements. Many satisfied clients return to Isabel to continue fulfilling staffing needs as required.

Beth Siegmann
Co-Owner / President
Beth brings years of experience in private service staffing and a genuine passion for connecting exceptional professionals with the families they serve. As Co-Owner and President of Casa Bella Residential Staffing, she is actively involved in every aspect of the agency, from developing client relationships and understanding the unique needs of each household to guiding candidates throughout the placement process.
Relationships have always been at the heart of Beth’s approach. Her experience working closely with high-net-worth families and private service professionals has given her a strong understanding of what makes a placement successful beyond experience alone. She believes the right fit comes from truly getting to know both the client and the candidate, with an emphasis on communication, trust, discretion and long-term compatibility.
Prior to Casa Bella, Beth worked with the Domestic Estate Management Association, where her passion for the private service industry began. Today, she continues to value the relationships she has built throughout the industry and takes great pride in the reputation Casa Bella has earned with both clients and candidates.
Outside of Casa Bella, giving back to her community is especially important to Beth. She is actively involved with local schools and organizations and enjoys finding ways to support the people and families around her. When she isn’t working or volunteering, Beth loves spending time with her husband and two sons—one proudly serving in the U.S. Marine Corps—cooking, cheering on the Oklahoma Sooners and, of course, being entertained by Boomer, the family’s much-loved Cockapoo.
