Latest Patient Center Updates

    (From Left) CEO Ray Weaver and CMO Gregg DeNicola MD

    Caduceus Medical Group is excited to announce, in its 20th anniversary year, it has finalized plans to renovate the historic Yorba Linda Packing House, originally built by the Yorba Linda Citrus Association in 1929. By 1912 farming had become a vital part of the community and business trade and many local residents grew orange and lemon trees.  However few had the time or money to send fruit to the store. In that year, farmers formed the Yorba Linda Citrus Association.  The association helped them build a packing house and send the fruit to stores all over the U.S.

    The interior design will pay homage to the local history and Caduceus will partner with other local organizations that share the same vision and spirit that makes our Yorba Linda community, the "Land of Gracious Living." The building will be the future home to its primary care, specialty, ob-gyn, pediatrics, and physical therapy center.  The existing offices will move over to the Packing House and Caduceus will truly become the one stop shop for medical care for the entire family! 

    To celebrate this milestone, Chief Medical Officer, Gregg DeNicola MD, shared the news with the Caduceus family and also made the announcements for the nominees of the annual company holiday gala, The Samme’s.  Nominees are chosen by staff in five categories- front office, back office, administrative, executive, and provider of the year.  The winners will be announced at the holiday ball later this holiday season.

    Caduceus Medical Group, which remains defiantly owned and managed by its physicians, is excited for its new journey in the Packing House and will be showcasing the progress once the renovations begin.  Stay tuned!

    Meet Our New Physician

    We are excited to welcome primary care provider Dr. Alyssa Tonelli to our Yorba Linda family practice. She was born and raised in Yorba Linda and played varsity tennis at El Dorado and went on to graduate from Stanford with honors.

    Afterward, she completed her DO degree at Western University of Health Sciences and pursued a family medicine residency with the Choctaw Nation Indians in Oklahoma. She is excited to be back home and serve the local OC community.

    Dr. Tonelli is a board certified family medicine physician who has a passion for preventative medicine and building one-on-one relationships with patients. She enjoys partnering with patients to help them achieve their goals. In her free time, she likes to travel, explore new restaurants, and spend time with family and friends.

    Reserve an appointment with Dr. Tonelli.

    We have also recently expanded our specialty services at our Irvine location, Caduceus Jamboree, to include ENT (Ear, Nose, and Throat.)  Our ENT specialist in Yorba Linda, Dr. Faramarz Shabdiz, will now be available for appointments for our patients that work or live in South Orange County.

    It's Our 20th Year Anniversary!

    In honor of our 20th year anniversary, Caduceus is highlighting employees each month that have been with our group since its inception.

    November Honorees

    Cindy Vineyard, Director of Claims

    Cindy began her career in the medical field in 1982 and joined Yorba Linda Medical Group shortly thereafter.  When the physicians formed Yorba Linda Family Physicians, she moved with the practice to the Packing House and then later started her career at Caduceus.  In 2003 she took over the responsibility of managing the claims department and is still going strong 16 years later! 

    Talia Wright, Director of Concierge Services

    Talia began her journey as an administrative assistant in 1993 and at that time there were only six employees! She was responsible for many facets of the operation including opening mail, filing, answering phones, ordering lunches for meetings, and scheduling provider meetings.  In the mid-to-late 90's, as the company grew, she held positions in many departments including human resources, payroll, benefits/eligibility, referral processing, and various special projects.
    In 2009, the concierge team was developed to provide meticulous patient care and outreach, and she assumed a role in the department and now manages a team of patient support specialists.

    The Caduceus family honors you both and are proud to have you on our team!
