"Should you have or know anyone that has this retched condition, please at least try Dr.  Patrick.  He is  worth the trip!” 

— Dennis’s Success With Trigeminal Neuralgia

Most of our Trigeminal Neuralgia clinical trial patients will be coming from out-of-state for treatment. Thus, you will need to plan your trip to visit us for 5 days Monday through Friday  for your treatment. 

Once you have been accepted into our program, we will send you a package of information, instructions, and a lab test for you to complete prior to your first in-person appointment with Dr. Patrick. Once we have your lab work in hand, Dr. Patrick will prepare your results to share with you on your first day with us here at the office. 

We have provided some 'where to stay and play'  links for you to assist in planning the details of your trip including nearby lodging, recreation, shopping and dining information, as well as current cultural and musical events.

Where to Stay

Chico is a charming small-town with big-city amenities. While you’re visiting, we suggest you stay at the Residence Inn by Marriott or the Oxford Suites, which are both within a few miles of the office and other conveniences. 

Where to Play

If you want to get outdoors, hike, bike or experience nature, explore Chico’s 3700 acre Bidwell Park designated as a California Regional Treasure.

If you would rather do some shopping and dining, or attend a concert or festival, check out lively Downtown Chico

Catch live theatre, music and plays at California State University Chico Laxon Auditorium.
