Ethics Committee

The primary function of the OPA ethics committee is to advise, educate, and consult concerns of the OPA membership about professional ethics. As such, we invite you to call or contact us with questions of an ethical nature. At times, ethical and legal questions may overlap. In these cases, we will encourage you to consult the OPA attorney (or one of your choosing) as well.

When calling someone on the OPA ethics committee you can expect their initial response to your inquiry over the phone. That ethics committee member will then present your concern at the next meeting of the committee. Any additional comments or feedback will be relayed back to you by the original contact person. Our hope is to be proactive and preventative in helping OPA members think through ethical issues. This committee is provided as a member benefit only to members of OPA. Please feel free to contact any of the following committee members.
