Is a pharmacist part of my healthcare team?

Yes ; No - Complex. Remember that while pharmacists have training in both molecules ; pharmacologic principles, they rarely spend the time or have the knowledge of a physician who actually focuses on assisting each individual. Their job is to sell treatments for store profit, without any necessary commitment to how effective/cost-effective, these will be for the customer long term. Focus is typically short-sighted.
Should be. A pharmacist is an important professional and should be part of a healthcare team.
