Estates, Wills, Tax
Mr. McCartin has been my attorney for more than a decade, and I am well pleased with all the work he has done for me. He is very professional, thorough and knowledgeable. He responds promptly to emails and telephone calls. He handled the settlement of my mother's estate in 2003 and my husband's estate in 2010. He has prepared my will (twice, due to changes in the family), my healthcare advanced directive and my power of attorney. In addition, he has prepared my tax returns annually since 2005. I recommend him highly with no reservations.

Elder care / elder law matters
I have known Tom for over 20 years. He is an outstanding Elder care and Estate planning attorney. He assisted me with elder care complications with my mother and her estate. He took the time explaining issues with me in great detail and made many helpful recommendations. He accomplished everything I ever asked of him promptly and professionally with compassion. I would highly recommend Tom. He is a pillar in our community. Tom is always there to lend a helping hand.

Handling Estates
Tom McCartin has handled two estates for me - one when I was executor of my Aunt's estate ome 7 years ago and that of my wife in 2012. His support and guidance during these two difficult periods of my life was caring and highly professional. His professional and skilled abilities shown through the entire process in terms of processing documentation and guiding me through issues related to distribution of assets. I have recommended him to other friends and colleagues. His office is very easy to reach by metro and he makes himself available by phone or in person easily. I think his hourly rates are competitive but he would be my go-to attorney regardless. Tom is a class act as an attorney and I am pleased to call him "my attorney".

Worth Every Penny Spent
I met Tom in April of 2015 (after my fathers passing) and Mr McCartin has taken my family and myself step by step through the estate process. Tom has over 40 years of experience in Estate Law and has done a wonderful job for us during this trying time

Handling Estates
Was recommended by a friend and was very pleased with our experience. Tom helped with updating my Mother's will and helped my husband and I with our estate planning. He is very accommodating to us and made it a very easy experience since.
