Our Team

When it comes to matters of mental health treatment, the clinical staff is where the true difference lies

Whether its focus is on drug & alcohol addictions, mental health illnesses, dual-diagnosis disorders or anything of the like, the effectiveness of a treatment center is largely determined by the quality, experience and dedication of its staff. In that spirit, we can truly affirm that our clinical and support staff is among Southern California’s finest. As you browse through our staff bios below, you will notice we have also included certification numbers for all of our LMFT’s and AMFT’s. We do this because:

  • We have a steadfast commitment to integrity & transparency
  • We are proud and honored to have each & every one of them on staff with us
  • Considering the importance of selecting the right mental or behavioral health recovery option, we strive to further simplify the due diligence process for you should you choose to do so

Should any question arise regarding staff information on this page, or for any reason, please call us 7 days a week at: (760) 777-7720
