On November 13, 2025, a disciplinary panel of the Texas Medical Board temporarily suspended, without notice, the Texas surgical assistant license of Marvin M. Walker, Jr., SA (Lic. No. SA00690), after determining his continuation in practice poses a continuing threat to public welfare. The suspension was effective immediately.
The Board panel found that Mr. Walker habitually used drugs or intoxicating liquors to the extent that, in the medical board's opinion, he cannot safely perform as a surgical assistant.
The temporary suspension remains in place until the Board takes further action.
