I am so thankful to have connected with John [Morrissey] who helped solve our chaotic legal difficulty last summer. I chose Siskinds simply through an online search for local Estate Law. John responded to my general inquiry in a timely manner and presented himself on the phone in a way that invoked confidence and trust. The expertise evident in that initial call was authentic.
John’s kindness, attention to detail, and great skill was so appreciated as we maneuvered a messy family situation. Through the long course of events, I could always count on John to be on top of things, never miss deadlines or important actions, keep me informed, explain procedures, and be patient with various oddities of the family situation. John’s professionalism, responsiveness, and expertise exceeded my expectations. John’s skill in dealing with the argumentative party was exceptional. I will also add, that both Reenya Koshaba and Heather Whitty were extremely helpful, thorough, and detailed in all their work and responses.
I will endorse both Siskinds and John Morrissey to anyone in need of legal assistance. I cannot express enough my gratitude and relief for John’s help in resolving this emotional family controversy. - D.W.

Elena [Ashford] and Angela [Belair] have been immensely useful in my application towards permanent residence. Elena's first hand experience as an immigrant brings out a compassionate approach towards her clients, and she is great with her knowledge of the processes involved. She takes a great initiative in ensuring that her clients stay on top of the documents and provides incredible insights into how the application would be viewed by the immigration offices. My application had come to a stand still, and after reaching out to her, it proceeded to approval within a month. Thank you to Elena and her team for all the great work! - C.P.
