Why Concierge Medicine?

You probably have experienced the frustration of waiting for weeks or even months to see a physician, only to find yourself languishing in a waiting room for hours. Physicians have less time for patients, feeling overburdened with administrative work, rather than direct patient care. The doctor is in and out before your questions and concerns have been adequately addressed.

Our concierge medicine medical practice limits our patient size to 400 patients which allows for ample time and dedicated attention to the individual patient and their needs. We have more quality time together, not only to treat complex issues, but to focus on prevention and wellness.

A concierge doctor and office that works for you, not for an insurance company, not for a corporation, and not for a large healthcare organization.

She joined Praeventus to practice the way she trained: 60 to 90 minute physicals, visits that do not get cut short, and patients who can reach her when they need her most.

I can call my doctor any time and any day and am very confident that I can find my doctor when I need him. He listens to me and explains everything in detail. Great team, very professional and always with a smile.

My husband decided to do the same. We are glad he did, for they found a 90% blocked artery which would not have been diagnosed just purely by a physical. He was immediately medically fixed.

I love Dr. Sobhani’s Executive service. It was the most comprehensive physical I’ve had. This is how medicine should be practiced: where the patient is treated with compassion and care.
