Please don't use "reach out" when we have perfectly adequate words such as "contact", particularly if you can't attach the relevant prepositions (if you really feel that you must "reach out", then I suppose you would "reach out to" - although why bother when you could simply contact, call, consult etc). NB whatever you do, say if you want to "reach out" to a whole group of people, don't suggest "reaching around" in a work context.
