Warning: I found this firm to be extremely unprofessional and found many reviews of heirs settling their parents’ estate reporting a similar bad experience. Their practice of refusing to share trust documents (unless court ordered) with a co-trustee who is legally obligated to execute the estate is highly unusual and suspect.

Bianca S. Bastos was professional and patient in explaining all of my legal documents. She made feel comfortable knowing I was new to the process.
The entire Sinclair Prosser Gasior team was available & ready to assit. This was a major step in my life in securing my trust and they assured me from the initial meeting they would handle everything. Every appointment they were prepared wirh my documents.
Thank you Bianca for making this experience less stressful
