Client Testimonials 

Never Disappointed

Maria Crimi Speth has been excellent with regard to all trademarking matters. I have relied upon her for many years, and she has consistently been highly professional, organized, and timely. Hire Maria. You will never be disappointed!



It is easy for me to say I trust Maria. After over a decade of working with her, she has proven she has my company's best interests in mind time and again. She communicates well and is highly reliable, always following through with what she promises. Most importantly, she always steered me in the right direction and saved me the most money on legal fees out of any attorney I have ever worked with. If you are looking for an experienced attorney who is highly capable, transparent and sincere, I recommend her highly.


Talented with Integrity

"Maria Speth has been representing our companies for almost ten years. When people ask about my attorney, I always say that if I had 4 sets of new radial tires, I would wear out every one of them, and would still not find someone as talented and with as much integrity as Maria. I have used attorneys for more than 30 years and Jaburg Wilk is the only firm I trust with all of our legal needs. Their legal staff is creative and they all know how to think outside the box, never missing a trick…all a must when doing business on the Internet."
