No. The right to represent oneself in court extends only to "natural persons." "Legal persons," such as corporations, LLCs, LLPs, LPs, etc. must be represented by an attorney at law.
There are exceptions for appearance before a government agency. So, were you appearing befoe the SEC, you might be able to appear without an attorney. Also, were you in small claims court, you could appear.
But, in regular State or Federal Court, an attorney at law is required to represent a corporation. No exceptions.
Hope this helps.
