Leather jacket repair

I guess repairer of golf bag and shoes would not be appropraite for the job.
It was cold in my office and thought swinging the club would warm me up. Oops the seam at the elbow split about 5cm. The stichings along the seam came off or loose. Apprecite if you guys let me know of anyone good in repairing leather jacket.
Thanks.

U wear leather jacket in the office ?
