Need treatment out of Hawaii

We live in Hawaii and are looking to get my 75-yr-old dad treatment outside of Hawaii. He was diagnosed in June with Stage 1B adenocarcinoma and is on his 8th round of MFolifornox. It's considered locally advanced because of vascular involvement. His CA19-9 have ranged from 28-17 since June. I've been so frustrated with his care because what the docs tell me run contrary to what I've read here and on PanCan and medical sites. His doc said NO ONE does biomarker testing or precision meds until AFTER SURGERY, telling me that I shouldn't believe everything I read online. He wouldn't do the genetic/biomarker testing so we went through PanCan and Tempus in mid-September. The results should get here this week or next. Met with a local surgeon a month ago who said he'd try to remove the tumor with another surgeon onboard to handle the vascular issues, but added that my dad wasn't a great candidate. I asked how often he does pancreatic surgery with vascular involvement and his experience is minimal. I requested a referral to a dedicated cancer center for the surgery. He sent a referral to UCLA (who hasn't contacted me yet) I'm wondering now, though, if I should take him somewhere for a second opinion and treatment to better prepare him for surgery. Another HUGE issue is that I go from doc to doc, leaving messages everywhere, but it's as the docs aren't in communication about my dad's case. I hear it would be different at a major cancer center. I would kiss the ground for coordinated care! Thoughts? His cancer was found accidentally after a bout of pancreatitis although I wish his PCP would have been concerned that he developed Type 2 diabetes at 74. I'm looking at Colorado because I used to live there and would have more support if I stayed with him during treatment and surgery, but ANYWHERE that would give him excellent treatment is an option. We'll take my dad anywhere and stay for pre and post surgery treatment to give him the best possible chance at recovery. Mahalo!
