Medicine Re-defined

An innovative health-management firm focused on what matters most: your wellness.

Dr. Paul Grewal

“When I left hospital medicine, I knew I wanted to start a different kind of private practice--one centered around what I love best about medicine-- the close, enduring personal relationship between patient and physician."

Concierge Service

You deserve a personal, customized treatment plan tailored to you, not a one-size fits all approach.   In our practice, getting to know patients is measured in years, not in minutes.


Our Practice

Discreet, Private Care

Comprehensive medicine in an elegant, private setting.

Medicine the way it used to be

Our practice is designed around one thing: restoring the close personal relationship between physician and patient.

24/7 Access to your Physician

As a member of the practice, you can reach your private physician by phone, email, or videoconference at all times.  In many instances, routine office visits can be avoided and prescriptions can be called in or delivered directly to your pharmacy.

Same Day Appointments

Same- and next-day appointments are available for our concierge members

Home and Office Visits

Your physician can visit you at home or at your office so you don’t have to interrupt your schedule.

Unhurried Visits

Comprehensive Physicals are scheduled for 60-90 minutes, and follow-up visits for 30-45 minutes.  You can spend as little or as much time with your physician as you need.

Our Values


We value your time. We make sure appointments start on time and take as long as you need to get all of your issues and concerns addressed.


A small patient base allows your doctor –always an M.D.– to leave no stone unturned when researching and coordinating your care.

Peace of Mind

When the unpredictable happens, your personal physician is just a cell-phone call away – and can even come to your home or meet you in the E.R.


Our Doctors provide guidance, coordinate with specialists, and consolidate your care so you never feel lost in the system.
