Care Philosophy

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."

I wish the stars went to 100!!! That is how I feel about Dr. Patrick Diesfeld ! He is amazing. He answers all my questions and empathized with me. I was a difficult patient and he took the time and explained everything clearly. He listened to my concerns and helped make me have a successful delivery. I highly recommend him.

Dr. Diesfeld became my specialist back in the days. I had ectopic pregnancy which took my Dr along time. My symptoms where never like a ectopic pregnancy. Which through my Dr and others off. My DR had called Dr D. in to look over me and bam I was in the hospital. I have had Dr D. since the 80's and I prefer him for my female stuff. He has great manners and very helpful also I would consider him as a friend. Great doctor I would give this man 10 Stars.. Thanks Dr Diesfeld
