THANK YOU to all who postponed/changed/sent photos during the beginning of the COVID-19 pandemic.  

Also please note that we are NOT Dignity Health affiliated and the recent Blue cross negotiations you have been hearing do NOT apply to either Gary Westbrock or myself.  

And we are NOT retiring!

We do, however, still require masks in hallways because of our Dignity health neighbors getting chemotherapy.  Thank you for being respectful.

Again, thank you for bearing with us. Please send your communications to [email protected] or [email protected], if any urgent issues arise.  

See you soon!


Karen D. Allen MD

Diplomate of the American Board of Dermatology

Fellow of the American Society for Mohs Surgery

Welcome! Thanks for visiting! We want all our patients to be informed decision makers and fully understand any health issues you face. That's why we've developed a web site loaded with valuable information about dermatology and skin problems and treatments. We encourage you to visit this site whenever you have concern about your skin.

Our web site also provides you with background about our staff, office hours, insurance policies, appointment procedures, maps, directions to our office in San Luis Obispo and other useful information. We know how hectic life can be and are committed to making our practice convenient and accessible. And we want you to feel confident that when you choose our office, you're working with a doctor and other professionals who are qualified, experienced and caring.

Please take a few moments to look through this site to get a better feel for our services. We also invite you to call our San Luis Obispo office at any time to request an appointment or ask any questions. Thank you.
