About me

I help clients find options for a fresh start through bankruptcy, assist creditors or companies that have claims against a debtor, and advise people receiving calls from creditors. I am certified in business bankruptcy by the American Board of Certification. My firm has a long history of successful results in the areas of insolvency. If I cannot assist you, I can find someone that will. Each case is different, and the key is to efficiently understand each client's goals and finding the path to reach them.  Outside of the office, I enjoy kayaking, snowboarding, and hiking.

  • Nicholas Joseph Bontrager

    I 100% endorse Mr. Birnberg. I have known him for over 10 years. He is one of the smartest, most hard working and diligent advocates I have ever met. I recommend Ethan as counsel to anyone or any business who may need assistance in his practice area(s)/expertise. You will not be disappointed.
