Our Service


Summit Nephrology was founded in July 2005 by a group of dynamic young physicians dedicated to treating the full spectrum of kidney disease from complicated hypertension to glomerulonephritis, dialysis, and post-transplant medicine. Nestled in the Sierra foothills, Summit serves the communities of Roseville, Rocklin, Lincoln, Auburn, Grass Valley, Granite Bay, and Orangevale. Our mission is to bring an academic quality of care to a boutique-style private practice. Central to our patient care model is face to face time with patients; we schedule one hour for new consults and thirty minutes for follow-up appointments. In a few short years we have successfully grown to be the dominant practice in our geographic market.

Mission Statement


“At Summit Nephrology, we create a comfortable and supportive environment that employs like-minded, knowledgeable, and conscientious physicians and staff. We provide compassionate, comprehensive, and individually tailored care for people with kidney related illnesses. Our practice gives our lives meaning, supports our partners in the medical community, and contributes to the well-being of our patients.”

Indications for Referral


In 2002, the National Kidney Foundation’s Kidney Disease Outcomes and Quality Initiative (K/DOQI) developed a staging process for chronic kidney disease (CKD) based on glomerular filtration rate (GFR). GFR may be estimated by creatinine clearance using several readily available calculations (MDRD formula link).  Many major labs are now providing an estimated GFR automatically when a serum creatinine is ordered. Both the International Classification of Diseases (ICD) and the Centers for Medicare & Medicaid Services (CMS)  have adopted CKD staging for billing and coding purposes.

Staging and Prevalence of CKD in the United States (Age ≥ 20 years) Stage
Stage ICD-10 Code GFR (ml/min) Prevalence (N) Prevalence (%)
1 N18.1 ≥ 90 5,900,000 3.3
2 N18.2 60-90 5,300,000 3.0
3 N18.3 30-59 7,600,000 4.3
4 N18.4 15-29 400,000 0.2
5* N18.5 <15 70,000 0.0
5* N18.6 <15 230,000 0.1

Table adopted from K/DOQI Executive Summary 2002. Data for Stages 1-4 from NHANES III (1988-1994) population of 177 million adults age ≥ 20 years. Data for Stage 5 from USRDS 1998. For Stages 1 and 2, kidney damage is estimated by elevated spot albumin-to-creatinine ratio of > 17mg/g in men, > 25mg/g in women on two measurements.

*Stage 5 is split into patients not yet on renal replacement therapy (RRT) (N18.5) versus those on RRT (N18.6), e.g. dialysis or transplant. More recent data place the Stage 5 population on RRT well above 300,000, with more than 80,000 living with transplants.

Referral to a nephrologist is recommended at CKD Stage 1 or 2 if there is unexplained proteinuria or hematuria or difficult to control hypertension, edema, renal calculi, or polycystic kidney disease. We recommend referral at least by Stage 3 for all diabetics and hypertensives for medication review and comanagement in order to slow the rate of progression of CKD. Patients often have sequellae of CKD like secondary hyperparathyroidism and anemia of CKD by this stage that may benefit from evaluation and management. Certain medications such as gabapentin and digoxin require dose adjustment by Stage 3, and certain medications such as metformin are contraindicated. Patients often develop edema, hyperkalemia, and metabolic acidosis by Stage 4 that may benefit from nephrology comanagement. Patients may be making preparations for renal replacement therapy (e.g. arteriovenous fistula for hemodialysis, peritoneal dialysis catheter referral, transplant referral) or may benefit from education about hospice from a renal perspective. Urgent referral is recommended at Stage 5 for renal replacement therapy or hospice education as well as the indications noted above.
