Can I book an appointment directly or do I absolutely need a referral?

When should someone be referred to an Internist or Geriatrician?

Referrals are typically appropriate for adults with complex diagnostic challenges, poorly controlled chronic diseases (like advanced Dyslipidemia (High Cholesterol) or Falls, Mobility & Balance Disorders), multiple interacting medical conditions, or unexplained symptoms.
