Genevra brings an insider’s perspective to her client’s issues. Prior to entering private practice, she was the sole in-house attorney for a prominent community foundation in Dallas, Texas, where she managed all issues related to legal compliance, board governance, and risk management. While in this role, she trained in-house staff, worked with ultra-high-net-worth donors, and consulted internal stakeholders on development and planned giving topics.
Genevra’s law practice focuses exclusively on the representation of tax-exempt organizations on a wide range of matters including governance, tax compliance, endowments, executive compensation, complex gifts, fiscal sponsorship structures, intellectual property issues, and employment matters. She counsels a range of tax exempt organizations including operating charities, community foundations, and religious organizations, as well as 501(c)(4) social welfare organizations, 501(c)(6) business leagues, and 507(c)(7) social clubs among many others. Genevra has been selected to the Texas Super Lawyers list (a Thompson Reuters publication) (2022-23) and by Best Lawyers® for Non-profit / Charities Law (2024-25).

"The Mendrygal Law team deftly navigated us through the transition from for-profit to non-profit. Our 1023 application was detailed with extensive exhibits to address any IRS questions before asked. We received our 501(c)(3) status with no questions or challenges, which is a testament to the thoroughness and experience of Danika and her entire team."
-Peter Poulides, Executive Director, Dallas Center for Photography

Genevra made us feel like a top priority and cared about what was best for us. We really appreciated what she did in getting the job done."

"My experience working with Mendrygal Law has been amazing. Genevra and her team were attentive and thorough and genuinely took the time to invest in me as a client. My nonprofit organization needed a fresh start, and they reviewed my previous work, guided me through the necessary steps, and helped me understand the process and the paperwork involved. Without Mendrygal Law, my nonprofit would have missed several important deadlines. I am grateful for their assistance and highly recommend their services."
