Frequently Asked Questions
How do I know which attorney is the right fit for my case?
Our attorneys are each capable of handling almost any kind of case, and we collaborate constantly. When you call our office, we ask a few questions about your matter and assign it to the attorney with the deepest experience in your specific need — Bob for business, civil, family, and probate matters; Cynthia for DWI and complex criminal defense; Nasrin for immigration. You're always welcome to request a specific attorney.
Can I work with more than one attorney at the firm?
Yes. When a case touches multiple practice areas — for example, a criminal charge that affects immigration status, or a business dispute with personal liability exposure — our attorneys collaborate so you get the right expertise across the board. One firm, one bill, complete coverage.
What languages do your attorneys speak?
Our immigration attorney, Nasrin Khill, is fluent in Arabic (native) and Hebrew, with full English fluency and written Spanish support. For other practice areas, English is our primary language of representation. If you need a language we don't directly support, we can arrange professional interpreter services.
Do your attorneys handle federal court matters?
Yes. Bob is admitted to the U.S. District Court for the Southern District of Texas and the U.S. Immigration Court. Cynthia is admitted to both the U.S. District Court for the Southern District of Texas and the U.S. Court of Appeals for the Fifth Circuit. Nasrin handles federal immigration matters in immigration court and before the Board of Immigration Appeals.
How do I schedule a consultation with a specific attorney?
Call (281) 579-3977 and let our office know which attorney you'd like to meet with — or which practice area your matter falls under, and we'll match you to the right person. You can also use the contact form on our Contact page. Most consultations are scheduled within one to two business days.
