Life Transition Management
Your Peace of Mind Starts Here
Clarity, care, and confidence for life’s possessions, decisions, and transitions.
Seriatim brings order to the tangible side of life, creating one clear picture of what you have, what matters, and what comes next. With discretion and care, we work alongside families and their trusted advisors to protect what matters today and create clarity for whatever tomorrow brings.
25+ Years of Expertise
Trusted by Fortune 500 companies, attorneys, financial advisors, and high net worth families with complex estates nationwide.
Every Phase, Every Transition
From proactive planning and estate documentation to relocation management and estate clearing, every engagement is guided by the CHAOS WHISPERER® methodology.
Peace of Mind, Delivered
We preserve legacies, prevent conflict, and create defensible documentation your advisors trust.
When life changes, the decisions pile up fast. Knowing who to turn to for guidance shouldn’t be one of them.
That’s where Seriatim comes in.
Guided by our CHAOS WHISPERER® methodology, we inventory and organize belongings, coordinate logistics and specialists, document important assets and records, and work with the family and their advisors to determine what needs to happen next. The result is one clear picture everyone can trust and act on.
Why the turtle? It represents the ability to carry your home with you, wherever life’s transitions take you. It’s a reminder that what matters most isn’t the walls around you, but what you choose to bring forward.

For Families: You don't have to know where to begin.
When a transition arrives, whether an estate to settle, a home to downsize, a move to manage, or a lifetime of belongings to sort, Seriatim brings the order.
We document what matters, identify what’s valuable, coordinate what needs to move, and leave you with a record you can trust through every transition that comes next.
For Trusted Advisors: See what the plan may be missing.
Important paperwork tucked away in a drawer. Valuables without documentation. Collections, memorabilia, and everyday belongings whose financial or personal significance may not be immediately clear. What’s inside a client’s home can create blind spots in even the most carefully managed estate.
Seriatim works on-site to identify, organize, and document what matters, giving you clear, thorough documentation your entire team can rely on to support legal, financial, insurance, and estate decisions.
When life gets complicated, we know where to begin.
Like the nautilus shell, we build in chambers, each phase larger than the last, while still carrying everything that came before it.
Growth doesn’t mean leaving your past behind, it means building forward from it.
That’s the thinking behind our CHAOS WHISPERER® methodology, a four-phase approach shaped by Sonya Weisshappel’s more than 30 years of work inside families’ homes, estates, transitions, and most personal spaces. It was built for moments when discretion, care, and expertise can bring clarity to what comes next.
Meet Sonya Weisshappel
For over 25 years, Sonya Weisshappel has been the trusted guide families and their advisors turn to when life’s biggest transitions feel impossible to navigate alone.
As the founder of Seriatim and the creator of the CHAOS WHISPERER® methodology, Sonya has built her practice on one conviction: that every family deserves a clear picture of what they own, what it means, and what should happen to it. She brought that philosophy to the page in her book, Confessions of a Chaos Whisperer, capturing the approach she has refined across more than 25 years of work inside families’ homes, estates, and most personal spaces.
From estate planning and downsizing to relocation and divorce, her work isn’t just about organizing possessions. It’s about preserving what matters and giving families the confidence that nothing will be overlooked.
