As the Managing Attorney at Sul Lee Law Firm. Diren Singhe instills a philosophy based on client-centric legal representation rooted in legal ethics, simple pragmatism, and Abraham Lincoln’s observation that the law is fundamentally the best reasoning of the wisest, applied over the ages “to the transactions and business of mankind.”

Following an early life spent all over the world from Europe to South America, California, and New York, Diren started his career as an executive at an energy industry startup in Houston before moving onto international commercial and intellectual property ligation, construction and design professional liability, fiduciary litigation, and then private company law. Diren is routinely called upon as an advocate in “bet the company” litigation and as trusted counsel in novel ventures.

Having served a broad spectrum of local, national, and global clients for several years, Diren has for the past decade focused on the representation of entrepreneurs, mid-cap companies, professional practices, and expanding family businesses with a presence in the DFW area, providing advice and advocacy as these they go from little more than tentative ideas, to becoming critical providers of jobs, goods and services, to becoming leaders in their respective industries and the broader society.

Diren has been active with various local Chambers of Commerce, serving on the board of the Greater Dallas Asian American Chamber for several years, and has served on the Judicial Nominating Commission for the City of Dallas. In his spare time, Diren and his wife, a physician, are avid dog adoption advocates, sharing their home with several Basset Hounds and other rescues. Diren is also an avid road cyclist, and enjoys traveling to events throughout the country as well as overseas.
