Penny has been fantastic at explaining the AAT treatment and listening to any concerns or trouble patients have with allergies. I have loved how professional and caring the staff at Cross Natural Health has been.

I have had food allergies and sensitivities to serveral foods for a long time. But Penny at Allergy Solutions of Idaho has helped me so much. I feel so much better now and have been cured of most of my allergies. I am still seeing her, she is such blessing!

I’ve suffered from grass allergies for years, unable to mow my own lawn! After just one treatment with Penny, I can now go outside and mow my lawn, play with the grandkids, and I am off all of my allergy meds! A miracle!


Dr. Karen Cross, FNP, ND – Owner & Medical Director

Doctor Karen Cross

Dr. Karen has been in the medical field for over 20 years. She blends her knowledge and experience in traditional medicine with naturopathy for true healing of the body. Dr. Karen has used blood testing for food sensitivities and allergies for years, but she was frustrated with the limitations on these tests as well as the expense to the patient. Through extensive research, she discovered “advanced allergy therapeutics.” It seemed too good to be true at first, but after a year of research and speaking with many other clinics and Doctors using this technology with fantastic results, she decided Idaho needed this option! Allergy Solutions of Idaho is owned and operated by Dr. Karen Cross, who also owns and operates Cross Natural Health. Penny Walde is the allergy specialist that does all of the allergy testing and treatments for us. You do not have to be a patient of Dr. Karen Cross in order to come in and get tested and treated! Penny will often consult with Dr. Karen if there is a tough case or particular medical issues.

I really like working with Dr. Karen. She’s warm, kind and friendly. She takes the time to listen to my concerns, and she’s very knowledgeable. I would feel very comfortable and confident in her ability to treat everyone in my family. I highly recommend her!

Karen treated me when I was suffering from terrible shingles and digestive issues. She helped me through the healing process and was there to answer my many questions and concerns along the way. She recommended some important diet changes and supplements and now I am completely well! I still see her for health maintenance to make sure I don’t let my immune system get down like that again. She is very caring and she truly wants to help people achieve health. I would recommend her to anyone. You won’t be disappointed!

I’m very excited about the healthcare options available to my family through working with Karen. I found her kind, sincere, knowledgeable and respectful of my choices as a patient (much appreciated).


I was really impressed. She knew what she was talking about. She had given me things to help me to get on track during her visit. I wanted to fix the root of the problem the most natural way and she understood that.
