Privacy Policy

Last updated September 2026

Pillai & Ganesan PLLC, doing business as Preventative Medicine by Science (“we,” “us,” or “our”), respects your privacy and is committed to protecting the information you provide to us.

This Privacy Policy explains how we collect, use, disclose, and protect information when you visit our website, communicate with us electronically, request information, schedule an appointment, or otherwise interact with our website and online services. It is separate from our Notice of HIPAA Privacy Practices.

Information we collect

Depending on how you interact with us, we may collect name and contact information, telephone number and email address, appointment and scheduling information, information submitted through website forms, information about the services you are interested in, a short reason for visit that you choose to type, website usage information such as browser type, device information, IP address, and pages visited, and information collected through cookies or similar technologies after you accept analytics.

Please do not submit diagnoses, medication names, or other detailed health information through the appointment form. A short reason is enough.

How we use information

We may use information we collect to respond to inquiries and requests, schedule and manage appointments, communicate with you regarding appointments, services, or administrative matters, improve our website and patient experience, maintain the security and functionality of our website, and comply with applicable laws, regulations, and professional obligations.

Health information that constitutes Protected Health Information (PHI) is handled in accordance with applicable HIPAA requirements and our Notice of Privacy Practices.

Protected health information

If you become a patient of Preventative Medicine by Science, information we obtain or create in connection with your healthcare may constitute PHI under HIPAA.

Our use and disclosure of PHI is governed by our Notice of Privacy Practices, which describes your rights and our legal responsibilities regarding your health information. This website Privacy Policy does not replace or supersede that notice.

Appointment requests

The appointment request form asks for your first and last name, email address, phone number, preferred contact method, and a short reason for visit. That information is delivered to the clinic so we can contact you about scheduling.

Email and web forms are not secure channels for detailed health information. Please do not include diagnoses, medications, or other sensitive health details in the form. A member of our team can ask for clinical details by phone or during your visit.

Communications

If you provide your telephone number or email address, we may use that information to communicate with you regarding appointments, appointment reminders, follow-up communications, requests or questions you have submitted, billing or administrative matters, and information about our services where legally permitted.

Electronic communications, including email and text messages, may not always be completely secure. Please avoid sending highly sensitive medical information through ordinary email or text unless an appropriate secure communication method has been provided.

Cookies and website analytics

Analytics cookies are set only after you accept them in the consent banner. If you decline, or ignore the banner, no analytics cookies are written and no measurement data is sent — not even anonymous pings.

If you consent, we use Google Analytics 4 to understand how visitors move through the site. This measurement is limited to non-identifying interaction data such as page paths, referral sources, approximate location derived from IP address, and device or browser type.

We do not send the contents of form fields, your name, or any health information to analytics. We do not use the site to build advertising profiles, and no advertising pixels are installed.

You can change your mind at any time by clearing this site's data in your browser settings, which removes the stored choice and prompts the banner again.

Third-party websites and services

This site links to services we do not control, including our patient portal, mapping providers, and third-party educational resources. Once you leave this website, the privacy practices of that service apply. Review their notices before submitting information.

How we share information

We do not sell or rent your information. We share it only with service providers who help us operate the site and communicate with patients, and only to the extent needed to do that work.

We may disclose information when required by law, to protect the safety of a person, or to establish or defend legal claims.

Information security

Appointment request details are kept only as long as needed to respond to your request and to meet our record-keeping obligations. We use reasonable administrative, technical, and physical safeguards designed to protect information in our possession. No website, electronic transmission, or storage system can be guaranteed to be completely secure.

Children

The practice sees patients age 13 and older, with parent or guardian involvement when required. This website is not intended to knowingly collect personal information from children without appropriate authorization. If you believe a child has submitted information to us without that authorization, contact us and we will remove it.

Nondiscrimination and accessibility

Preventative Medicine by Science does not discriminate on the basis of race, color, national origin, sex, age, or disability. For accessibility requests, contact Seema Pillai at the phone number or email below.

Your privacy rights

Depending on the nature of the information involved and applicable law, you may have rights regarding your personal information. To ask what website information we hold about you, to correct it, or to ask us to delete it, contact us using the details below.

Patients also have specific rights concerning their protected health information under HIPAA. Those rights are described in our Notice of Privacy Practices.

Changes to this privacy policy

We may update this Privacy Policy periodically to reflect changes in our practices, technology, services, or applicable law. The updated version will be posted on this page with a revised effective date.
