About the firm
The person who actually answers your call.
MSG Tax & Accounting was built for business owners who want more than once-a-year tax prep. Based in Rancho Cucamonga and serving clients across Riverside, Ontario and Southern California, we offer year-round strategy, guidance and real partnership.
Manny took what he learned at a large firm in Irvine and rebuilt it for self-made, fast-growing owners — the ones big firms usually overlook. Whether you are scaling e-commerce, managing rentals, running trucks or leading a medical practice, you get clarity and a plan.
Off the clock, you will probably find Manny shooting hoops, cheering on the Lakers or Dodgers, or out in the Southern California sun.
