All cancellations incur a $20 administrative fee andmust be received in writing or electronically seven days prior to seminar. No refunds will be issued on cancellations received after that date. Substitutions are welcome at any time. Developmental Resources, Inc. reserves the right to cancel any seminar in the event of insufficient registration, in which case a full refund will be returned. If for any reason the seminar is not held, Developmental Resources' liability is limited to a refund of the registration fee paid. If you miss the cancellation deadline, and are unable to either attend the training or send a substitute, we will issue a voucher that is valid for two years. It is transferrable to a colleague and may be applied toward any of our professional development events.
