Areas of Practice

Corporate structuring and restructuring

Corporations require a very different legal approach, and it’s why we advise mediation or arbitration before stepping into litigation. With the consistent introduction of varying revenue streams and distribution channels, the opportunity for profit grows, but so does the complexity. That’s where we come in.

Mergers and Acquisitions

Demystifying mergers is one of the things TEIL Firms, LLC does best. M&A is not just for publicly traded companies. Companies of all sizes find occasion to acquire, or merge to expand, transition their interests, or even downsize. Talk to us today to get an expert legal opinion on how you and your company can sell, or acquire new assets while safely evaluating risk.


Business and the happenings of it in the age of media is ever-changing, so the law and its practitioners must adapt quickly. TEIL FIRMS, LLC strives to anticipate these changes so you can focus more on creating the business of your dreams.


The startup and small business marketplace is still a new and fierce frontier that requires legal advice from attorneys who are deeply entrenched in the particularities of venture financing. Our firm gives you an holistic approach, so your company can get the best competitive advantage.

Business negotiation

The internet, software, and technology are so pervasive that we can’t remember having ever lived without them. They make our lives simpler, but behind the curtain are fluctuating challenges in protection and monetization—challenges that our firm stays two steps ahead of.

Business Fraud

Business is a little like life. Much of the difficulties you encounter can be avoided with careful planning, and preparation - but some issues cannot be avoided. Protecting a brand or even a single design involves intellectual property, copyrights, trademarks, and patents. Don’t find yourself unprotected, arm yourself with legal expertise and get ahead of the curve.


We must all obey the great law of change. It is the most powerful law of nature.
— Edmund Burke
