About Feldstein Family Law Group P.C.

Feldstein Family Law Group is an Ontario firm that practices family law exclusively, with offices in Markham, Mississauga, Vaughan, and Oakville that together cover York, Peel, Halton, and Durham Regions. Founded in 1994 by Andrew Feldstein, the firm has grown to eleven lawyers with more than 100 years of combined family law experience among them. Its work spans divorce and separation, child custody and support, spousal support, division of property, and separation agreements, along with collaborative family law, mediation, and unbundled legal services for clients who want to handle part of their case themselves.

Andrew Feldstein graduated from Osgoode Hall Law School and was called to the Ontario bar in 1992, after starting in a broader corporate commercial practice before moving into family law full time. Feldstein was appointed to the inaugural Dispute Resolution Officer panel for Newmarket in 2010 and served as Executive Member at Large for the Ontario Bar Association's Family Law Section in 2019. The firm runs on a paperless system, aims to return calls and emails the same or next business day, and hosts a monthly public Q&A called Ask Andrew that is now in its eighth year. It has also received the client-voted Top Choice Award for family law services for 15 consecutive years.
