Self-Financial Disclosure*: Dr. Prakasam is a paid consultant/advisor/speaker/researcher to multiple national and international pharmaceutical and device manufacturing companies.
*Dr Prakasam is a legally paid consultant, speaker and researcher for many for profit companies in the field of endocrinology and diabetes Dr.Prakasam continues to have the same relationship with many of the companies for several years. Many of the drugs and devices that my patients are prescribed are made by those companies. However, Dr. Prakasam always believes in providing the best professional advice and care for his patients and the business relationship does not influence his prescribing decisions. Dr. Prakasam believes in patient’s choices, formulary choices and cost for the payors and the patients when making medical decisions or suggestions. Many of the medicines and devices used in endocrinology do not have generic alternatives. If you ever have any questions on Dr. Prakasam's business interests, do not hesitate to ask him as he feels it is a privilege families give him to take care of their loved ones. Since he has a vast international and national experience along with his medical degrees from three continents and a Masters in Health Administration, it is natural that he is a sort-after consultant and speaker in the field of medicine. However, he has practiced medicine in the most ethical and honest way for over three decades just as his father advised him when he entered medical school in 1981.

Sarah Woods RN MSN CPNP

Sarah Woods is a pediatric nurse practitioner who graduated from UCSF in 2018. She has had type 1 diabetes since 1995 and was seen as a patient at Dr. Prakasam's clinic from diagnosis. Since that time it has been her dream to provide compassionate care to children and families managing this relentless disease, she is thrilled to be providing that care at CEDE.
     Before nursing school Sarah was involved in research at UCSF studying the effects of a behavioral intervention on depression and diabetes distress in teenagers with type 1. She led groups teaching teens stress management techniques and using cognitive behavioral therapy to reframe negative thought patterns. The connection between mental and physical health is a passion of hers and she believes addressing the psychosocial aspects of diabetes is just as important as addressing the blood sugar data.
     She discovered the magic of Bearskin Meadows diabetes camp as an adult and has been excited to be a nurse there for the past few years. Teen camp is her favorite and she loves backpacking with teens, even with the 12am and 2am blood sugar checks.
    In her spare time she loves working out, whether running, spinning, yoga or weight lifting and is on a forever quest to not get low during workouts. She also loves to bake and can carb count most baked goods on sight. Now that she's back in the Sacramento area she loves spending more time with her nieces and nephews and re-exploring the area with her husband.

Olga Yefremenkova RN FNP

I come from a military background of having served for ten years in the U.S. Army, after which I became a Family Nurse Practitioner, who specialized in pediatric endocrinology. My journey to becoming a nurse practitioner started when my daughter was diagnosed with type one diabetes. My daughter started receiving services at the Center of Excellence for Diabetes and Endocrinology, and I was grateful for the staff’s support, care, and expertise. I wanted to be able to help children just like my child and joined the team. I am thankful for the opportunity to now be part of the CEDE family
