I want to change my PCP. Seeking guidance on process

Hello Connect.
My problem: I need to find another Dr.
I'm in a new city+state and arrived here recently so I still know only a few people. I chose my Dr from an insurance list based on his credentials. But what he looked like on paper doesn't translate into good medical care. Plus his interpersonal skills are tainted by his 'issues.' It's just unworkable. The Nurse Navigator, who had been working with me, was displeased with him also and was concerned also that I'm not receiving competent care as well.
PCP is in a large Internal Medical group. The area I moved to doesn't have much high level care to begin with.
My other specialists (Opthalmologist, Neurosurgeon, Gyn) are in the same campus in different buildings.
I'd like to stay in the same large Internal Medicine group. This is the issue that's at the center of my challenge.
The Internal Med Drs are highly political when it comes to the ego/business aspect of their practice. That's not uncommon, but it's more pronounced here than I've ever seen before.
I want guidance on how to begin and implement this change.
I was considering reaching out to the Medical Director but that may be politically incorrect with counter productive results. I don't know. I want to ask for a referral from my Neurosurgeon I respect but I was referred to him by same PCP. They worked together closely in the past when PCP did a stint in ER.
Plus, I don't know who in the lg group in accepting new patients. It's a tight market of availability here There is a certain Dr. in the group who I think may be a good fit. I can't ask questions privately bc you have to leave an open VM or use patient portal (which I don't use) with their group as the only means of communication.
I'm not in competent medical hand with this Dr or I'd endure him. I need another Dr for certain. My options are limited by my location and I'm walking in the dark in finding another.
My Opthalmologist is also PCPs Dr so I can't ask him.
I intend on handling the separation from PCP as a "no - fault" decision.
I'd like guidance on the order of the steps I need to take I don't know what this process should look like in action. I don't want to be left without a PCP, which could happen here.
I had my former Dr for 16 years of excellent care and a wonderful interersonal therapeutic relationship. I was living in a large area with top hospitals. I was also previously in the medical profession so I knew who was who. I'm in an entirely new scenario now. Never anticipated being in this situation.
Thanks so much for considering my problem and offering your ideas or experience. I appreciate the opportunity to get your input.
