A genuine approach
In May of 2020, I approached Siskinds Law Firm to represent me with the Passing of Accounts for my handicapped son.

I was referred to Lawyer Leanne Kuchynski and Law Clerk Heather Whitty. I left our first meeting feeling confident that these two people were best suited for our needs.

They have a genuine approach, are kind and understanding, and extremely bright when handling legal matters.

They were particularly efficient at dealing with the PGT and courts, expressing our concerns and wants moving forward. The end result was judgment in our favour.

I highly recommend Siskinds Law Firm. This is my second experience with this firm, and like my first, I found Ms. Kuchynski and Ms. Whitty to be experienced, professional individuals who work hard to get the best results for their clients. - S.R.

A pleasure to work with
I highly recommend Leanne Kuchynski at Siskinds Law Firm in London, Ontario for matters related to wills and estates. Leanne has been a pleasure to work with from the beginning to the end of the process. She advised us on how to proceed and kept in close touch even though we do not live in the area. Thanks to Leanne we obtained a fair settlement. She is a credit to the legal profession. - P.P.

Brilliant Strategic Thinking & Outstanding Work Ethic 
I am sincerely grateful to Leanne Kuchynski for representing my wife and I in what we considered to be an unprecedented situation. Leanne's compassion, practical advice, openness to feedback, brilliant strategic thinking and outstanding work ethic led to the most optimal outcome while maintaining a superior human experience. Despite the harsh realities of the situation, I felt extremely comfortable that our best interest was Leanne's utmost priority and was confident in her demonstrated ability. She was professional and exceptionally thorough, yet remained remarkably caring.

I used to have a somewhat cautious disposition towards lawyers based on past experiences; however, Leanne completely restored my faith in the profession and earned my unquestionable loyalty for all future legal needs. - S.M.

Kind, Compassionate, & Understanding
Thank you so much for all your help! You, Jenny and your team at Siskinds have been kind, compassionate and understanding but most of all professional. I just wanted you to know how grateful I am to have had you in my corner. Thank you so much! - K.L.
