At Cohasset Medical Group, we pride ourselves on providing patient wellness and excellent customer service.  

NO APPOINTMENT NECESSARY. 

Our walk-in provider can help with all types of illness and injury.  If you cannot get in to your primary care doctor then we can help you with easy access to our walk-in providers. 

We take most major insurances and Covered California. Please call and confirm that we are contracted with your insurance carrier and we do the billing.

For those without insurance, we have a convenient cash pay at time of service of $75.00 dollars that covers a one illness visit.  Any medication or injection required will be added to the cost.


OUR MISSION

To improve the health of our patients by providing exceptional care, a wide range of services, convenient and timely appointments with compassionate service. 


Dr. Foster is the type of physician that you hope you can find. Caring, patient, intelligent and well informed. He has become one of our family.
