How the Network Works
Functional medicine often requires a team approach. Our referral network ensures you have access to the right specialist at the right time.
Assessment & Referral
During your consultation, Dr. Crifase identifies whether specialty support — labs, pharmacy, or a co-managing practitioner — would benefit your case.
Coordinated Handoff
We connect you directly with the right provider, share relevant clinical context (with your consent), and ensure seamless continuity of care.
Integrated Follow-Up
Results and progress notes flow back to Dr. Crifase so your treatment plan stays cohesive, informed, and aligned with your goals.
