Arnall Golden Gregory has promoted a transactional partner to corporate practice co-leader and strengthened its ability to work with international clients with a new addition previously at a South Korean firm who wants to make Atlanta an international arbitration "hub." 

The Am Law 200 firm named Michael C. Thaler as firmwide co-chair of its corporate & finance practice and added Lance B. Lee as an international arbitration partner in Atlanta from Seoul-based law firm LIN earlier this month.
