There are some 'organizational therapists' who basically are therapists, but they deal with professional people in business / organization settings to try and help people maximize their outputs / performance. A good one... Could be really very helpful indeed :-)

You know... There really isn't a great deal of shame about going to see someone like this. In fact... Therapy is often thought of as a thing that only basically healthy / well people can do (psychoanalysis is thought to be unsuitable for all but the most highly functional) and a lot of people consider it a relative 'luxury' that is expensive and (sometimes) a little time consuming. It really is great that they are prepared to invest the time and money so that you can do it.

I would say that disclosing the depression thing is something that should be completely up to you. The first thing I would check with this person is the extent of the notes they keep and who has access to them. It might be that your employers want some kind of progress notes, you see, and I (if I was in your situation) would want to know what kinds of things the person you see would be putting down on that so I would know whether I felt okay about disclosing the depression thing or not.

It is perfectly possible to talk openly and honestly about how you feel at times without mentioning the magical label 'depression'. The label doesn't really add anything to the explanation of the symptoms anyway (it merely redescribes them).

Who knows what this person may be like... But it is possible that it is helpful to you. Not just with respect to work, but maybe with respect to other aspects of your life in terms of enhancing your functioning and helping you feel happier healthier and more productive.
