Any experience with OB's in either Women First Health or Contemporary Womens Care?

Does anyone have experience with the Doctors in either of these practices? Both in West Orange. For reference, their names are listed here: 

Women First: Sylvester, Youngren, Lo, Sansobrino, DeSantos

Wondering about beside manner, professionalism, office staff, really everything. Anything you can share would be awesome! Thanks so much.

I am very familiar with Contemporary Women's Care.  I can say unequivocally that all doctors there are very knowledgeable, have wonderful bedside manner and are extremely professional.  I am forever indebted to Dr. Sadural who delivered my twins 10 years ago.  I wait to get booked with him and actually look forward to seeing him every year.  He is a blessing to his profession and was instrumental in getting me through a high risk pregnancy.  I can't say enough good things about him.

I loved Dr. Wimmer at Contemporary Women's care.  She delivered my youngest child in 2000.  I recently left the practice only because I am post-menopausal and I found another gynecologist better suited to my needs.

I'm a fan of Women's First.  Dr. Sansobrino delivered my son last year -- he's wonderful.  Very professional, great bedside manner. 

Thank you all for the feedback; it's both helpful and reassuring!
