Care Philosophy

This content was provided by Dr. Diesfeld "Drs. Diesfeld, Pattamakom, and midwife Roseann Tibbs have assembled this unique, highly-trained team to provide INDIVIDUAL CARE in a BOUTIQUE manner.

  We are not a mega group, nor do we wish to deliver every baby in Ventura County.

  Rather, our small group provides highly-individual care for the patient.  We are unusual in that we strive to deliver our own patients, 24/7.  We are not in a large call group!

  We also are unique in having a full-time dedicated midwife, Roseann, available to care for you, throughout your pregnancy and delivery.

  We have on-site ultrasound, and enjoy immediate proximity to the hospital.

  We invite you to join the thirty thousand plus patients who have enjoyed their obstetric experience with us.  "We want you to feel at home here, to know that you can count on us and that we care about you and your health. Treating you with kindness, respect and compassion is the philosophy our team lives by every day.""
