Jason's Testimonials
Young, energetic, highly motivated
I found Maria Rasul to be a young, energetic, highly motivated and very understanding lawyer with strong dedication to her career in law. She along with Jason Koh dealt with my case most professionally and continue to advice me through. The best part is the initial free of cost consultation in which they guided me most transparently letting me know what I am up against and preparing me regarding the dos and don'ts.
