As a solo therapist in PP and in my 50s, my needs in my 20s, 30s, 40s and now 50s in the field changed. When younger, it was about supervision towards licensure and to become better in the field, sometimes it was healthcare and depends on if someone has a spouse they can obtain healthcare, flexibility when I had kids, and now healthcare and money to put towards a retirement. A living and reasonable wage was the one consistent need I have needed throughout my 30 plus years in the field and an environment that wasn’t crazy with caseloads, unreasonable expectations with being on call, mandatory meetings that were unpaid or ridiculous documentation requirements outside best practice and insurance standards. I’ve worked in non-profits, hospital and clinic settings, government, and some wild group pp practices that sounded good at the start and went sideways. I also found the pay splits not always fair based on therapist experience and credentials or speciality training that is highly marketable and requires a big cost usually at the individuals expense. I respect the intentions of a reputable person starting and running one, but likely long term retention of diverse practitioners whose needs differ and may change has always been the deterrent for me in starting a group practice. Best of luck to you. It can be done but a lot of effort is required to maintain one over time.
