According to the new regulation rules of the insurance and investment adviser market, Deutsche Vermögensberatung has now to declare that they are not independent brokers but rather "gebundene Agenten" since their company is the main distribution channel for AachenerMünchener and Generali insurance. Therefore you have to anticipate that you will not receive unbiased and independent financial advise but more a hard sale of insurances and related products from a rather small selection of the market.
Of course any large financial advise company has good and bad advisers and I am not saying that everyone of them will be just out to sell you stuff you could get better and cheaper elsewhere... but it is indeed a corporation where the comission is divided in a structure so that people in the higher echelons of the organisation profit a lot from the sales of the lower culis and thus encourage strong and hard sales while good sales results only will get you up the corporate ladder...
I would advise not use them, if you real want advice from a big financial adviser institution, pick one that is more independent like MLP or AWD (even though some of my critizism above also fits to them as well).
Or you just might want to try out a real independent financial advisor... like me, for instance
