South-Jersey Family-Owned Business Attorney

Mariel was raised in a multigenerational family of entrepreneurs, which provides her with a unique, insider’s understanding of the dynamics that drive – and sometimes complicate – family-owned businesses.

Family businesses involve sensitivities and interpersonal dynamics that set family-owned businesses apart from other organizations. Mariel understands that those dynamics create both a sense of pride to drive the organization into the next generation as well as complications that require empathy and understanding.

Her approach blends legal skills with emotional intelligence to meet the complex needs of families in business together which allows her to leverage this unique understanding to deliver practical, forward-thinking legal solutions that align with each family’s business goals, values, and legacy.  Mariel understands that the success of a family-owned business depends on thoughtful planning, clear communication, and the ability to adapt to change and her legal advice and counsel is uniquely crafted for each business to help strengthen their foundations and prepare them for long-term success.
