I hired John D’Angelo approximately six years ago to represent me in a custody matter. Based on my experience, I was extremely disappointed with both the representation I received and the outcome. Going into the case, I believed there was substantial documentation and evidence supporting my position and serious concerns involving my former spouse, including a history involving police and allegations of violence, abuse, harassment, and stalking. Despite this, the case ultimately resulted in an outcome I felt was unjust and completely contrary to the evidence I believed was presented. What was even more frustrating was what happened afterward. On multiple occasions, my former spouse violated court orders. I brought those violations to my attorney’s attention and asked for assistance in addressing them through the court. Despite acknowledging that violations had occurred, my attorney repeatedly declined to pursue the matter. I struggled to understand how I could spend thousands of dollars obtaining court orders that, in my experience, were not meaningfully enforced when they were repeatedly violated. I was also told that the hearing had been unfair and unjust, yet when I asked for assistance with an appeal or with pursuing a change of judge, I was not provided the help I was seeking. When I needed assistance with other legal issues related to my case, I was frequently told no or that the firm would not get involved. After six years, the primary thing I feel I was left with is approximately $30,000 in legal debt and a profound lack of confidence in the representation I received. I understand that no attorney can guarantee a particular outcome in court. My concern is the level of advocacy, communication, and willingness to pursue the legal remedies I was asking for. Based on my personal experience, I would not recommend John D’Angelo or this firm to anyone seeking representation in a custody or family-law matter. If you are considering hiring this firm, I strongly recommend that you thoroughly research your options, ask very specific questions about how your attorney will handle violations of court orders and appeals, and make sure you are comfortable with the level of advocacy and communication you can expect before signing a retainer.

Daniel Walsh was very professional and knowledgeable. He took the time to explain everything clearly, answered all of our questions, and made the process easy to understand. We left feeling confident about what needed to be done and what steps were necessary to complete our will. We truly appreciated his guidance and expertise throughout the process

I’ve worked with Megan M Corollo and her paralegal for a few years now. Unfortunately, this year has been very disheartening working with them. I have been trying to get in contact with them for about 2 months now. Calling, texting, and via email. I’ve had none of my questions answered, I receive one message and then get ignored and it continues. I hired them to get legal assistance, I have been a client for years and to be treated as such is frustrating. All I wanted was assistance on some information and felt like I could take it from there. I hate that I had to resort to a review.

We hired John a few months back to represent my 14 year old son. John met with us right away and made us feel so much better about the situation. He was informative, professional and listened. He explained things well and my son’s case was thrown out! I would be pleased to work with One Law Group in the future if we ever need to.
