We did not issue a certificates for 1,000 hours. This would be fraudulent. We issue certificates that may have been made out in the past for 10 Hours at a seminar. Other people have altered their seminar 10 hour certificates, which is why we now write in the words "Ten hours". If someone is claiming my husband has given him a certificate for 1,000 hours this is not legitimate. If you tell me where you are located, perhaps I can put you in contact with a legitimate, certified instructor with us. Thank you for letting me know about this.
