Team TaxMama®  

All of your instructors are Enrolled Agents who’ve passed the EA Exam – they know what you’re going through. Most  have Master’s Degrees and lots of other experience and training in various areas of taxation. All have had teaching or training experience. We’ve all been practicing longer than we’d care to admit.

Eva Rosenberg, MBA, EA

Eva revived and restructured the EA Exam Review course at UCLA Extension, then taught it through Eva’s Tax Class for several years.
Eva earned an BA in accounting and MBA in International Business, Eva was trained in national and (then) Big-8 CPA firms, and has been in private practice for decades.
Publisher of one of the most popular and accessible tax websites – – Eva and Team TaxMama® have answered thousands of questions for taxpayers over the years – as a free community service.
Eva trouble-shot businesses and represented taxpayers at audits and with collections issues for decades. She was the go-to girl for tax pros who couldn’t resolve audit or collections problems, finding quick and equitable solutions.
Author of best-selling books and hundreds of articles, Eva wrote a nationally syndicated tax column for Dow Jones’ MarketWatch for nearly 15 years.
Eva passed away in August 2023 after a brief illness. Her proteges Susan, Ish and Stephanie — Team TaxMama — successfully taught Part 3 of the course as well as redid Parts 1 & 2 in Winter 2023. Team TaxMama is committed to continuing TaxMama’s EA Course in the TaxMama spirit in honor of her legacy.

Ish Dalal, MS, EA
Teaching in Parts 1, 2 & 3

While Ish’s roots are in Computer Science/EE, his true calling emerged after he delved deep into complex international tax issues. At the end, he thought, why not make his love of taxation official?

But it was January 2018, and major changes to the EA exam were imminent. With his family’s support, Ish prepared for and passed all three EA exams (with all ‘3’s) in February 2018.

With newfound exuberance, Ish immediately hurtled into TaxMama’s Free Forum, answering questions guerilla-style — and annoying Eva (TaxMama)! That’s how they became acquainted. Eva quickly thought it best to co-opt Ish’s enthusiasm into something more productive–and they began collaborating to improve the EA course.

In a previous life, Ish detoured into academia, serving as an adjunct professor and hoping to join its ranks. Eva always wanted him to teach for the EA course since they first met…and now he is!

Ish lives in Northern California and maintains a small boutique tax practice focusing on clients with international/foreign aspects.
