More about Dr. Patrick William Diesfeld

A reputation for advanced, personalized care 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've been in Ventura since 1985 and have earned the trust of women from all walks of life. I think I've come to be known just as much for my personalized care as for the advanced women's medicine I provide. That's exactly the way it should be.\" Dr. Diesfeld's credentials and interests: BOARD CERTIFIED: American Board of Obstetrics & Gynecology FELLOW: American College of Obstetricians & Gynecologists MD: State University of New York, Buffalo, NY RESIDENCY & INTERNSHIP: Los Angeles County–USC Medical Center, Los Angeles, CA RESIDENCY DIRECTOR ASSISTANT: UCLA Medical Center Ventura Campus Ob/Gyn Training Program, Los Angeles, CA MEMBER: International Society of Gynecologic Endoscopy, American Association of Gynecologic Laparoscopists, American Urogynecologic Society, American Institute of Ultrasound in Medicine, American Association of Ambulatory Surgery Centers, American Medical Association, California Medical Association, Ventura County Medical Society INTERESTS: Dr. Diesfeld's leisure-time interests include saltwater fishing, boating and snow skiing with his wife, Dr. Estela Diesfeld, and their twins.
