I have known Rabbi Grunewald for many years and have had the pleasure of discussing legal and halachic matters with him on several occasions. I have no doubt that his wide-ranging knowledge, razor-sharp analytical skills, and resourceful, problem-solving approach would render his dispute resolution service of great benefit to anyone in need of assistance of this nature.

Rabbi Grunewald has a highly analytical mind and an ability to work and converse with all types of people in varying situations. His one-to-one skills are excellent and his ability to hone in on the real issues in a mediation situation, whether they be religious, civil or commercial, are superb. His knowledge of Torah, Rabbinical Law is a real asset especially when combined with English Law.

I instructed Rabbi Grunewald to assist me in a Din Torah case. From the outset he gave me a great deal of time to ensure that he fully understood all of the details of the case, and he prepared a very authoritative set of arguments which summarised why my case would fit into different halachic parameters, no matter which way the Dayanim would view it. Rabbi Grunewald researched my case well, and was very authoritative on areas of Halacha in Choshen Mishpot. He came excellently prepared, was able to confidently rebut the arguments of the opposing side, and was calm throughout the process. I was incredibly impressed with Rabbi Grunewald as a To’en and would have absolutely no hesitation in giving him the highest recommendation.
