About me

Before starting medical school, I worked on farms, in marketing, as a dishwasher, grocery salesman, waiter, convenience store manager, line cook, and emergency medical technician. I’ve always enjoyed working in fields that have me face-to-face with people and require strong teamwork. My own experiences in the health care system helped me strive to become a dedicated healer and champion for a better system of health care delivery.

About my practice

You and I are a team. I’m here for you. Together we’ll work through problems toward the best possible outcome. I promise I will work toward developing a trusting relationship with you and your family to make sure you get the care that you want. What most people don’t know about gastroenterology is that deaths from cancers of the GI tract outnumber those of breast and prostate combined. I help prevent cancers from ever developing, particularly colon cancer. I also perform advanced therapeutic endoscopic procedures with the latest technology available to help you. I treat people the way they want to be treated. I listen, take time to learn your perspective and understand the problem while being compassionate and keeping you involved in the decision making. If you need something different, then simply let me know. We work as a team with our specialists, pharmacists and others to coordinate your care.

How I thrive

I love being outside. Enjoying the space and cooking outdoors with my family and friends is very satisfying. My family is the most important part of my life. I have a wife, daughter, son and two dogs. I enjoy tennis, cross-fit, hiking, golf, chess, landscaping and reading books that help me improve myself, plus some fictional series. The occasional Netflix binge watching is fun, too.

Information in this online directory is updated periodically and applies to commercial plans underwritten by Kaiser Foundation Health Plan of Colorado. The availability of physicians, hospitals, providers, and services may change. To verify whether a provider accepts Kaiser Permanente plans, contact the provider directly. Current provider information is available at kp.org/locations. This information is updated within 72 business hours of receipt from providers. Kaiser Permanente of Colorado attempts to ensure the online directory contains up-to-date information. However, providers are responsible for notifying kp.org of any changes to their information, and untimely communication may result in outdated provider information appearing on the website. The printed directory is current as of the date of publication. Kaiser Permanente is not responsible for use of outdated directories.

Kaiser Permanente uses the same quality, member experience, or cost-related measures to select practitioners and facilities in Marketplace Silver-tier plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business. The measures may include, but are not limited to, HEDIS/CAHPS performance, member/patient complaints, patient safety scores, hospital quality measures, and geographic need. Members enrolled in KFHP Marketplace plans have access to all professional, institutional and ancillary health care providers who participate in KFHP plans' contracted provider network, in accordance with the terms of the members' KFHP plan of coverage. All Kaiser Permanente Medical Group physicians and network physicians are subject to the same quality review processes and certifications.

Kaiser Permanente uses the same geographic distribution consideration to select hospitals in Marketplace plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business.

Information about a practitioner is provided to us by the practitioner or the practitioner's network, or is obtained as part of the credentialing process. An authorization or referral may be required to access some providers in this directory. If you have questions, contact Member Services.

Referrals to affiliated/contracted physicians/providers in Denver/Boulder

Affiliated/contracted physicians/providers are not part of the Colorado Permanente Medical Group (CPMG). They are physicians/providers who have a contract with the CPMG.

If your CPMG physician decides that you require covered services not available internally from CPMG, he or she will refer you to an affiliated/contracted physician/provider.

You must have a written referral to the affiliated/contracted physician/provider in order for Kaiser Permanente Colorado to cover the services. A referral is a written authorization from Kaiser Permanente for you to receive a covered service from an affiliated/contracted physician/provider.
