About me

I was born and raised in South Dakota but I have lived in Colorado since the mid 1980s. I enjoy the outdoors, the people of Colorado and the practice of medicine. My wife, my children and I have a strong compassion for caring for people. I love my work at Kaiser Permanente.

About my practice

I am an Internist who specialized in Allergy/Immunology.I continue to help innovate new more effective ways to deliver the best value in healthcare. Our Allergy Department is a cohesive forward looking group that values quality allergy care in a timely and courtious fashion. We care for patients with allergies/asthma/immune system problems/drug reactions and adminster allergy injections. I am using our electronic medical record and information technology to start providing telemedicine care for patients in distant clinics. Most notably I have been described as a passionate patient advocate. My home office is Rock Creek Medical Offices. Additionally, I see patients at the Frisco Medical Offices.

How I thrive

To thrive I think it is important to balance work and hobbies with family life. My wife and I have raised 2 children in Denver and continue to be involved in their lives as best we can. We try to model compassion and caring in our lives and find that practice to be very rewarding. I believe in a healthy mind and body and good relationships with my family and friends. Despite being an allergist I have 3 pets whom I treat as family.I truely love animals and this planet we inhabit. I am nearly old enough to retire but I will continue to work at Kaiser Permanente because I believe in our mission to transform the face of this world's healthcare to a more caring/effective business that improves people's lives and sense of well being.

To find:

  • a Kaiser Permanente provider’s office hours, search our facility directory.
  • network providers’ office hours, call their office directly.
  • providers in your plan or accepting new patients, call 303-338-4545 or 1-800-218-1059 or 711 (TTY for the hearing/speech impaired), 24 hours a day, 7 days a week.

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 considers the following factors/criteria as it builds and maintains provider networks:

  • Size and demographics of the population to be served;
  • The inventory of provider types required to serve the population and using practitioner to member ratios and geographic access standards metrics to ensure adequacy;
  • Application of rigorous credentialing criteria encompassing but not limited to educational training, licensing, professional experience, board certification, and professional references.

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 KFHP (Kaiser Foundation Health Plan) products and lines of business. 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 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.

To report any inaccuracies in the directory, contact Member Services. Members may also report inaccuracies at kp.org/memberservices.

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

Affiliated/contracted physicians/providers are not part of the CPMG (Colorado Permanente Medical Group). 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.
