Can't answer and here's why. Some psychiatrists or therapists could be terrible. Depends on the rent, number of offices, whether or not you accept insurance, Medicare, Medicaid, or are private pay.
You have a therapist there and they're good that's great. If they are less than this it's bad.
I have noticed the more "therapy" patients the less the office will tilt towards the severe more physiological illnesses such as schizophrenia. I've also noticed that therapists aren't typically experienced with psychosis in general and if they see your patients they might inadvertently get a psychosis patient.
E.g. one of my schizophrenia patients started seeing a therapist in the office. She complained of his psychosis as if she was inexperienced in dealing with it, and I don't know why she didn't give disclaimers or express the limitations of therapy and continued treating him if she really didn't want to see a schizophrenic patient as if this was completely new territory for her. He started seeing her without telling me and when she got him as a patient she never once approached me to get information on him so I didn't know about it until well after it started. She also wasn't exactly doing a good job with him by the time I found out about it.
The garden-variety therapist in a private office (and yes of course there's exceptions) are dealing with mild issues or personality in a superficial DSM sense. If you have therapists in your office they have to know that you deal with stuff that's outside that unwritten norm, that the two aren't exactly compatible and what both provider types want to share. (That's not to say what they do is easy and there's plenty of functioning people with severe issues that therapy will benefit, hence why I used the term "superficial.")
The pros I thought would happen with therapists in the same location didn't foment often. E.g. there were therapists where they'd refer me someone and never provided me with a heads-up, if I checked the therapist's records most of the time I couldn't even read their notes. Sometimes if they did give me a heads-up and came to my office, instead of presenting it to me like a physician they'd go overboard and talk about the patient for like 25 minutes in between patients when I really only had a few minutes. They never had the "present the patient" in a succinct manner training you get in the hospital. Now this wasn't all therapists but it was enough for me to never expect it to bridge well most of the time.
