Pointers for depression counseling , help in NYC?

Hi New Yorkers, would love direct, or personal recommendations as well as feedback. I know I can call 311 for clinic referrals, but I would like personal input if possible.

Recent months since this winter, I have been worried about a late 20's young friend (distant relative) that has become close to me in recent years. He's has all the usual job and financial issues as well as often social aspects (he is usually all of his friends' support, not the other way around). He used to party a lot (drinking, dabbled in drugs), but less so in the last 1-2 years. Lately, his job has cut hours and he has been much less active, sleeping a lot, etc. He can just cover his rent (room share). He denies being depressed, but I think this is standard for a lot of guys who don't think they are depressed, just "moody" sometimes. He tells me he is not drinking, or doing drugs at this point (I hope so, but I am not good with figuring out that stuff). Also he is a creative, artistic type, unconventional in a lot of ways, but tends to be very independent as well.

I am worried about him and feeling helpless, not sure if there is anything I can do if he isn't showing urgent depression, just life changes so far.

Would love any advice, personal stories, as well as recommendations for counseling and therapy.
