Ernesto Chavez (CRD: 4315877) faces a new pending claim on BrokerCheck over an investment made in 2018. The customer alleges $180,000 in damages, and no arbitrator has ruled on the claim.
Soreide Law Group obtained the following information, which is available to the public, on FINRA’s website under, “Disciplinary and Other FINRA Actions, August 2017.”
Mark Charles Koehler (CRD #2873947, Chadds Ford, Pennsylvania)
was barred by FINRA for the alleged refusal to produce FINRA-requested information and documents after FINRA began an investigation following receipt of a tip that he had allegedly engaged in unsuitable trades in the account of a senior client.
FINRA’s findings stated that during its investigation, FINRA also reviewed the alleged trading in certain other of Koehler’s client accounts, including those associated with a second client and her senior client parents.
FINRA sought to investigate allegations of, among other activity, whether Koehler engaged in unsuitable trading, including short-term mutual fund switching and excessive trading in client accounts, placed undue influence on the second client before her death, and failed to disclose to his member firm his status as a named beneficiary in the second client’s will.
