About Our Concierge Internal Medicine Practice.
As a member of our concierge medicine practice, you’ll receive truly patient-focused and personalized healthcare. Our practice size is smaller than a traditional practice which means we’ll have more quality time together—not only to treat complex issues but to focus on prevention and wellness.
You’ll have peace of mind knowing that we offer little to no waiting for appointments in a fully sanitized, clean, safe environment.
-Dr. Amanda Collins-Baine & Dr. Jenifer Drummond
Changes at Darien Signature Health
We are excited to share some important updates and enhancements to Darien Signature Health that we believe will improve your experience with us.
New In-House Billing Process
As a part of our ongoing efforts to provide more efficient and personalized service, we are transitioning to an in-house billing system. As of August 1, 2026 we will no longer bill patients through Specialdocs Consultants. In the coming days, as your concierge membership fees come due, you will receive an emailed invoice. The invoice will include a secure payment link to HELCIM, our new billing platform, where you can conveniently review and submit your ACH or credit card payment. Stored credit cards will also be used for office visit balances. Payment by check is accepted as well.
If you have any questions regarding your invoice, billing or payment options, please feel free to contact Susan Murphy at 203-286-5604, who will be happy to assist you.

What Is Concierge Medicine?
Concierge medicine, also known as membership medicine, is a relationship between a patient and a primary care physician in which the patient pays an annual fee or retainer. In exchange for the retainer, doctors provide enhanced care, including principally a commitment to limit patient loads to ensure adequate time and availability for each patient.
