About me

I grew up in New England and completed my medical training in Massachusetts. I then spent two and a half years working in rural areas, on the Navajo reservation in northeastern Arizona and in Brush, on the eastern plains of Colorado. I have chosen to work with Kaiser Permanente in Greeley in order to work as a part of a team and live in an area with more cultural and social opportunities.

About my practice

I am board certified in pediatrics and internal medicine, so I care for people of all ages. This means that children do not need to transition to a different doctor when they reach adulthood and that I can care for all members of the family, though I do not have training in obstetrics and gynecology. It is important to me to get to know my patients and partner with them to assist them in staying healthy. I believe in a healthy lifestyle as a strategy for remaining healthy and feeling well.

How I thrive

Being active outdoors is my favorite strategy for managing the everyday stresses of life. I especially enjoy being near water, such as hiking to waterfalls or lakes and canoeing or kayaking. Reading allows me to expand my knowledge and/or escape into another world. Another passion is dancing, and I have participated in it from a very young age.

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are responsible for notifying kp.org of any changes to their information, and untimely communication may result in outdated provider information appearing on the website.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 Kaiser Permanente is not responsible for use of outdated directories.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.
