There's a reason why LHHH has so many 5 star reviews. Sean and his team are incredible at what they do. We were in a rush to get urgent answers for a pending office license we had questions on... We sent an email and had a phone reply in less than 10 minutes. We feel they are one of the best law firms around and took a lot of stress away from any potential delays. If you need help with business law or estate planning, Sean and his team @ LHHH should be your go-to law firm to get this done. We trust them and will continue to use them moving forward. Great work everyone!

I had been thinking about estate planning for a long time but was concerned about how much work it would entail. The worksheets provided, while time consuming, were easy to follow and complete. The first consultation was comprehensive as was the signing of the trust documents. The team made sure I understood everything I was signing and that it was reflective of my wishes. The cost was also better than others. Highly recommend this firm.

My wife and I recently completed our will and estate plan with Sean Hagen at this firm and could not be happier with the process and the end result. They were really accommodating and helpful throughout the whole process. We feel like we have a solid foundation to ensure the financial health of our family whatever happens next! Thanks for your time and energies Long Hagan Huff-Harris!

I needed a full estate plan and The very thought of it was paralyzing. Sean and his team were amazing. They were informative, suggestive, explained things thoroughly and gave me the space and time to put the plan together. There was no pressure at all. They were up front about the cost, which was reasonable and walked me through every single overwhelming detail of my estate plan.
The entire staff were patient, kind and thoughtful. I highly recommend using this firm. I did my research, spoke to several other lawyers and firms and really felt this was the firm most dedicated to doing what was right for their clients. They are also local to Roslindale and very clearly want to be a part of the community. I 100% support and recommend this firm.

Attorney Hagan (who I worked with) is a talented attorney who has outstanding personal skills. I approached him for help with a legal matter that was outside of his typical area of focus, and I was impressed with how he familiarized himself with details that he does not routinely encounter. I highly recommend him.

It is impossible to overstate the excellence and uniqueness of this law firm. Not only are their lawyers highly skilled at what they do (trust planning in my case) but they are also compassionate individuals who on two occasions made time for me in emergency situations and within hours completed work which was desperately needed. Needless to say, this is not the scenario which usually plays itself out in life and I could not be more grateful to them.
