About Our Physicians

Learn more about the practice and our network of physician consultants.

Our network of experts

At MD For Patients, each of our physicians and consultants was invited to join the practice due to exceptional qualifications and experience in their field. They believe strongly in our mission – to better serve patients with direct-access care.

Some of our affiliated physicians and consultants are employed by and compensated directly by our practice. Others choose to donate their earnings to a fund that allows more patients in need to take advantage of our services.

A note to patients

Our practice is constantly growing. We also have access to a network of expert physicians across a number of fields. If you need a consultant in an area not currently listed on our Services page, let us know. We will reach out to our network to try to meet your needs as quickly as possible.

Get in touch with us to request your consultation.

MD For Patients focuses on providing direct patient consultations - and consultations with / assistance to patients’ local healthcare providers.

If you are an attorney seeking assistance from one of our consultants as an expert witness, or a patient either in the midst of, or considering initiating, legal action with regard to your consultation request, it is certainly possible that we can assist you, but please call us at the number below rather than initiating a consultation request through the website form.  We will be in touch with you.

This differentiating process is necessary so that we can provide our clinical patients and their care providers with the best direct care and customer service possible - without the confusion that might arise if the intent at entry is related to litigation.

Get started by providing your basic information and we will email you with next steps.

Primary Contact Form (with Purview link)

We require the name and contact information of at least one of your current local healthcare providers.  If an unanticipated critical finding is identified during your consultation, we must be able to reach one of your local providers on your behalf.

This provider need not be in the same specialty as your consultation request. Please provide this information in the Referring Physician section on the Expert Opinion Request form you will complete during the intake process.
