Firm Information
Overview
At The Atashi Rang Law Firm PC, we guide individuals, couples, families and business owners through every stage of estate planning and administration. Based in Walnut Creek, California, we provide comprehensive counsel in estate planning, estate tax planning, property tax planning, business owner estate planning, trust administration, probate and estate administration, and prelitigation trust and estate disputes. Whatever stage of life our clients are in, we help them prepare thoughtfully for what lies ahead.
We understand that life rarely moves in a straight line. Careers shift, families grow, health changes and financial circumstances evolve – and we believe every client deserves a legal partner who anticipates these changes rather than simply reacting to them. Our approach centers on building lasting relationships grounded in trust, clarity and foresight so that our clients feel confident their affairs are structured to protect what matters most.
Our firm is led by principal and founder Amir Atashi-Rang, who is licensed to practice law in both California and Texas. He holds the distinction of being a certified specialist in estate planning, trust and probate law through The State Bar of California Board of Legal Specialization, and he earned a Master of Laws in taxation, giving our clients access to sophisticated tax-aware planning strategies alongside traditional estate services.
Getting started with our firm is straightforward. After an initial inquiry, we send a detailed intake worksheet to understand each client's unique circumstances, then arrange a meeting with one of our experienced attorneys to map out next steps. We also invite prospective clients to take advantage of a complimentary 20-minute consultation, giving them the opportunity to discuss their goals before committing to a plan.
From our Walnut Creek office, we proudly serve clients throughout the greater San Francisco Bay Area and beyond, extending our reach from Northern California down to San Diego. Wherever our clients are located, we remain committed to helping them safeguard their legacy, minimize tax exposure and plan with confidence for the future.
