Edward R. Hammock  has been practicing law in New York State for more than 45 years.  As the result of the times we are living in, many of our current events, today’s political climate and people’s attitudes in general, he is more motivated, enthusiastic, and committed to seeking justice than ever before.  It is his vast experience and history in this business that gives him the right to say what few lawyers in the state can say - he has “done it all”. Ed’s nickname in criminal justice circles is “Mr. Parole”.  There is a reason for that – keep reading and you will learn why.

He worked as a New York State Probation Officer while attending law school.  He has been a prosecutor a number of times – first in the New York County District Attorney’s Office where he worked in the Homicide Bureau.  Then he worked as a special prosecutor for the NYS Attorney General’s Office investigating the Attica prison riot of 1971.  That was the largest and worst riot in New York State prison history.  He worked for a time as the Executive District Attorney supervising several bureaus for the for the Queens County District Attorney’s Office.  He was the executive director of a major NYC drug treatment program for several years.  He also served as Deputy Commissioner for the NYC Department of Investigation.  For more than 7 years he was the Chairman of the NYS Board of Parole and the Chief Executive Officer of the NYS Division of Parole.  He has taught at a number of New York City schools, i.e.; St. Johns’ University School of Law, Fordham University, John Jay College of Criminal Justice and the College of New Rochelle.

When Ed went into private practice in 1985 he never imagined the overwhelming need for someone with his knowledge and background in what is commonly referred to as the “back end of the criminal justice system”.  Criminal attorneys are familiar with the “front end”, i.e. arrest, trial, plea negotiations, sentencing; however few are familiar with the front AND the back.  What happens to a defendant after he is sentenced is something most criminal attorneys don’t know and have no need to know.  Because of Ed’s unique combination of experiences, he has become the “go to guy” in criminal justice for back end system issues and concerns.  


Donna M. Sullivan​
Practicing criminal law is the last thing Donna Sullivan thought she would end up doing with her law degree.  How did it happen?  When she was attending St. John’ University School of Law, her criminal law professor was a guy named Ed Hammock who had just gone into private practice.  Because of Donna’s previous paralegal experience, she was quickly identified as Professor Hammock’s go to person for research, writing and office practices. 

She continued working for the Professor, caught the criminal defense bug and has been working with “the Professor” ever since. She has learned her lessons from him over the years and from her own experiences in the different parts of the criminal justice system.  

Ms. Sullivan does trial preparation with Prof. Hammock and usually second seats him at trials.  She prepares various motions and memoranda of law as required for matters we are handling.  She handles all the administrative responsibilities and duties of our office.

Hammock & Sullivan represent diversity to their clients and to their profession.  They are members of difference races and different generations.  They enjoy working with and for people who are from all cultures, all ethnic groups, all worlds.  Their comfortability with cultural and ethnic differences  and their respect for all people make them an unusual and dynamic combination in advocating for their client’s rights.
