I manage and work in a coworking space (a shared work space for freelancers and other independent workers) and there are a few coaches who also work there. All of them offer a first coaching session free and my sense is they do good work. Here are three that you might want to consider:
Irena Štěpánová. She also runs a business that trains in-company trainers so they are ready to train on specialized soft-skill topics. You can get her contact info at her company website, http://www.trainingcookbooks.cz/o-nas/tym/
. She doesn't advertise her coaching there, but I have experience with her and think she's quite good at a one-on-one level. She speaks English.
Martin Bednář is an experienced coach and also speaks English fluently. Here's his website: http://www.adfonte.cz/martinbednaren.html
Stuart Farleigh focuses on family business, but might also be interesting if you're working in that domain. Here's his website: http://www.familybusinessunit.com
You can also learn a little more about Stuart and Irena on the coworking space members page: http://www.locusworkspace.com/members/members
If you'd like introductions to any of them, just let me know and I can facilitate, but you could also just contact them directly.
There are also a couple of online coaching organizations with presences in the Czech Republic that you can use to search for a coach that matches your requirements:
The European Mentoring and Coaching Council: http://www.emccouncil.org/eu/en/find_mentorcoach
The International Coach Federation's Czech site: http://www.coachfederation.cz/cz/hl...ucu-icf-cr.html
Hope this is helpful.
