          Congratulation Class of 2022


          Yen Truong MD, Class of 2012 -  Maternal Fetal Medicine, Kaiser Permanente, San Leandro:

          “My time at SCVMC, or as my co-residents and I lovingly called "Valley", was transformational. The attendings, nurses, and other residents have shaped me into the physician that I am today. The experiences there cannot be found in any other training program. I felt very prepared coming from Valley and going into MFM fellowship (and practice). There are lots of opportunities for leadership, exploring your interests, and for making lifelong friendships. Lastly, the patient population at Valley is wonderful and some of the most amazing people you'll meet.”

          Kerry- Ann Kelly MD, Class of 2015 -  OB/GYN Generalist Highland Hospital;  Director, Women’s Reproductive Health Equity Fellowship, Alameda Health System

          “I transferred into SCVMC my second year because I wanted a better education.  I soon learned that I got exactly what I asked for.  After graduating from the program, I can say that I received comprehensive, evidence-based, generalized OB/GYN training.  My colleagues have often re-affirmed my sentiments.

          It is hard being in residency training, especially OB/GYN.  At SCVMC, I appreciate that I was a resident who didn't have to worry about having a different set of standards applied to me or being treated differently because of the way I look.”

          Nkiru Chuba, Class of 2017, MIGS Fellowship, UC Irvine

          When I look back on my residency, I have fond memories of my time at Santa Clara Valley Medical Center (SCVMC). Don’t let the title of a “county program” fool or dissuade you from this residency program. We were often at the forefront in development and adherence to the practice of evidence-based medicine. We had the pleasure of working with and for a diverse patient population with an equally diverse range of pathology. The hours were long and we worked hard, but we took pride in knowing we were making a difference to improve health outcomes of our patients. This sentiment is shared amongst faculty, nursing and ancillary staff.  These qualities were match by our in- depth surgical training and lack of surgical fellows, which allowed for development of the competence and confidence most graduates share upon graduating.  It was this exposure that spearheaded my desires to pursue a Minimally Invasive Gynecologic Surgery fellowship. The support I received from my fellow residents during the application and interview process, as well as the faculty support and encouragement surpassed my expectations. I am truly grateful that same support and encouragement have continued when looking for my first job and to this day. Now, residency is not all work and no play. As the culture of medicine evolves and burn-out became more common place, SCVMC maintained work-life balance as priority. We went on class trips, regularly socialized amongst the residency classes and even on occasion hung out with our attendings too (who can forget Dr. Hugin’s Christmas parties)

          There was a feeling I couldn’t shake when I interviewed for residency at SCVMC. That feeling was that no matter how hard, challenging or intimidating an OB/GYN residency can be, I would be supported and that these people weren’t just my colleagues.  Rather, they were my community, my team, my mentors and lifelong friends.  Knowing what I know now and reflecting on my past experiences, if I had to do it over again, I would choose SCVMC every time!

          Kayvahn Steck-Bayat MD, Class of 2017 – MIGS/ Integrative Medicine Fellowships

          “As a graduate of 2017’s residency class, it is with great pleasure that I write a strong letter of support for Santa Clara Valley Medical Center’s OB/GYN residency program.  Some of my favorite aspects were the very supportive faculty/staff/co-residents, the high quality of hands-on teaching and personal mentorship, and the day to day patient population where I truly felt like I was making a difference in their lives.  The Attendings at Valley are not only talented and experienced, but also driven by compassion and a pure love to best serve our patients and Residents.  The environment was friendly, supportive, and encouraging.  

          I was able to flourish as a resident and pursue fellowships in Minimally Invasive GYN Surgery (MIGS) and Integrative Medicine at the University of Arizona College of Medicine, Phoenix.  My choice to pursue a MIGS fellowships was driven by my passion for surgery, and surely not to make up for a lack of training in residency.  In fact, I entered fellowships with great confidence surgically and clinically and I thank the SCVMC Faculty for their dedication to teaching.  I am now in community practice in Ojai, CA and have been able to confidently care for a wide range of patients from simple to complex.  I am grateful and humbled that I was able to complete residency at SCVMC.  In retrospect, it is without hesitation that I would choose to complete my Residency at Valley and do it all over again!”

          Nayda Kondrahov MD, Class of 2018 – OB/GYN Generalist, Sutter East Bay

          “After graduating, I accepted a generalist position at Sutter East Bay Medical Foundation and felt very well prepared to practice on my own. My residency at Valley has prepared me very well to practice both obstetrics and gynecology and overall made me a well-rounded physician. I feel confident in the operating room and on labor and delivery and work efficiently in the office. 

          I think the strengths of the program include 1) experience in vaginal surgery 2) advanced laparoscopy with MIGS verified attending 3) no fellows (meaning residents are primary surgeons in most cases) 3) great training in family planning 4) complex obstetric patients and 5) Valley's unique culture. 

          We have very special patients, coming from all backgrounds, and many who don't speak English and have minimal resources. It made our work a lot more gratifying to be able to help someone who needs it the most. I felt very well supported by my attendings who are very passionate about teaching and resident well-being. 

          If you are considering to practice right after graduation or if you are pursuing a fellowship in urogyn, family planning, MIGS, or MFM, Valley will prepare you well.“

          Kyle Graham MD, Class of 2019 – OB/GYN Generalist , Salud Para La Gente, Watsonville:

          “You don't realize how well SCVMC prepares you for practicing on your own until your first call shift as an attending. You surprise yourself with how much you know, how natural you manage complicated patients, and how skilled you are in the OR. Valley gave me these skills and confidence. After graduating from Valley, I had a few extremely complicated patients while practicing as the only obstetrician in a low resource rural setting and time and time again I literally thought to myself, "Thankfully I've seen this at Valley" or "Thankfully I did this in Residency." Valley prepared me and gave me the confidence to immediately be successful as a solo practitioner. 

          Particularly, with regards to the OR, in Residency you operate with your Attendings but after Residency, often there is no assistant surgeon and you are alone in the OR. Valley gave me the operative skills and confidence in the OR to perform solo surgeries. Particularly, vaginal hysterectomy is something you will get a lot of experience with at Valley.

          As a county facility, Valley offers a training experience where you will see rare and complicated cases. You are supported by a wonderfully skilled team of MFM, OBs, Gyn Onc, laparoscopic specialists, and family planning experts so that you always feel safe while practicing. Valley is the type of residency you want so that you are prepared for the world of surgery and medicine after your training is finished.”
