Since 1999, Seriatim has helped people navigate some of life’s most complex and emotionally charged transitions.

Founded by Sonya Weisshappel, Seriatim began with a simple but powerful belief: when people are facing change, what they need most is clarity, care, and steady guidance.

Over the years, our team has supported hundreds of clients across the country, from New York to California, including executives, families, seniors, and individuals navigating moments like relocation, estate planning, loss, or major life change. We also work closely with trusted professionals, financial advisors, attorneys, real estate brokers, interior designers, and architects, who want their clients to feel supported beyond the paperwork.

At the center of our work is the Chaos Whisperer System, a proactive approach to preparation that helps people organize, document, and make sense of what they have before it becomes a burden for others.

This is not about getting rid of things or rushing decisions. It’s about bringing calm where there is chaos, clarity where there is uncertainty, and protecting what matters most.

That has been our work for more than two decades, and it continues to guide how we show up every day.
