Casa Blanca Tax & Mortgage
Quality tax service since 1995.

Our Team

Passion. Service. Diligence.


My mother, Suzanne Jimenez, and I founded Casa Blanca Tax & Accounting together in 1993 on Paramount Boulevard in Downey, California. My wife, Roni, and I shared an office with her for two years before moving to Los Alamitos to open Casa Blanca Tax & Mortgage in 1995.  At the time, we had approximately 1,000 loyal friends and clients. Fast forward 20 years and we added three more Licensed Tax Professionals and have prepared more than 10,000 returns in the past three years.

Sandra was preparing tax returns for Steve's mother in the early 80's. Sandra moved out of state, came back and was re-recruited to join my team in Los Alamitos. Sandra’s experience and expertise are miles above the average preparer. She is involved in measureless volunteer work and was recently honored by Maddie’s Closet with the “Love, Hope & Joy Award” - recognizing outstanding contributions by an individual to improve the lives of children battling cancer.
