About me

I was raised in Erie, Pennsylvania, and graduated from Jefferson Medical College. I completed my Internal Medicine training at Fitzsimons Army Medical Center and practiced as an internist in the Army for three years at Fort Lee in Virginia and Fort Polk in Louisiana. I have practiced at the Hidden Lake Medical Offices since 1997.

About my practice

I chose Internal Medicine as a specialty because I enjoy taking care of geriatric patients with a wide variety of complex medical problems instead of focusing on one part of the body or organ system. I listen and seek to understand my patients' questions and concerns. Our teams at Hidden Lake meet daily to discuss ways to improve the way we take care of patients. I am impressed that Kaiser Permanente allows us the freedom to innovate and find new ways to take care of patients. For instance, I can offer my patients convenience through email, phone and video visits. I feel that I am empowered to provide patients high-quality health care at Kaiser Permanente. I don’t feel pressured to avoid ordering tests or medications that are right for the patient, but I will choose more cost-effective approaches. I am detail oriented and I really enjoy making patients happy by helping to solve their medical problems.

How I thrive

I like to fish, hike with my wife, exercise at Red Rocks, and spend time with my family.

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) anytime day or night.

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are responsible for notifying kp.org of any changes to their information, and untimely communication may result in outdated provider information appearing on the website.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 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.

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

Questions? Please call or visit your local Member Services department.

The TTY number is now 711 for all KPCO

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.
