With Michelle's help, our family is now sleeping through the night!…read more Just last night we put our 6 month old down per the guidance and support Michelle has given us and he slept from 7:30pm straight through to 6:30am with zero fussing and a big smile on his face when I picked him up to start the day. She is knowledgeable, helpful, flexible and empathetic to each family's needs and preferences - what more could you need from a sleep consultant?! Her background in nursing and experience as a mom of three also helped to reassure us that her methodology was sound and we were in great hands. I cannot recommend her enough!

Full disclosure - we think we have an incredibly easy baby and were farther along than many in our…read morepath to sleep training. Still, we needed an expert to make the final few tweaks to our overnight routine and hold us accountable. Through a series of questionnaires and in-depth phone conversations, Michelle tailor-made a sleep training plan for our baby, including daytime nap intervals and feeding schedule. She listened to our questions & concerns, and thoughtfully addressed them all. She followed up with us daily, either by phone or email. And as she predicted, within 3-7 days we saw significant changes in our child's sleep behavior. He fell asleep consistently & on his own without a bottle, pacifier, or swaddle. Michelle went above & beyond by supplying us with tools and materials for the future, when our baby gets sicks, travels out of time zones, and reaches new developmental milestones. Michelle offers different tiers of engagement; we chose the over the phone option and we still had excellent results. Her services were well worth the cost!

I have been struggling with ptsd, depression, anxiety, sleep apnea, alcoholism and addiction. He recommended me to go to AA and rehab. He also got me a c pap machine for my sleep apnea due to me being 270 lbs, I used to be 190 until I fell into everything. He helped me through the many years, I have been sober for almost 6 years, I am back down to 190 lbs and no longer use the cpap. And, yes, none of my problems will go away, there is no cure, but he has helped me learn to control them. No more suicidal thoughts, even after attempting 3x. Still sober, and after today's appointment he told me I have come a long way, and I agree, I was a mess back then. I highly recommend Dr Parham. He pushed me to get myself better and I have. Thank you so much!

The semi annoyed message from a male at 925-325-2744 said this was my 3rd and final call. This is a lie. I laughed so hard and had to replay the message multiple times. I have all calls back to June 2024 and voicemails back to December 2019 on my phone. This is the very first call. Now, I called more than a dozen times between November 16, 2024 and December 21, 2024....AND I followed up with an email letting them know that I was done reaching out and they needed to call me because I was requesting a new provider and a new sleep center. Which, I immediately did in January 2025 because this company was a joke. I tried to be give grace because of the holidays, but.....it's the middle of MAY! 176 days since the day I was referred is when they finally bothered to respond. I've have already seen a new sleep doctor AND already had my new sleep study. Six months is not an appropriate care time for a specialist. I was able to have my sleep study with 4 days of seeing the new specialist...FOUR days, but these folks think 6 months is acceptable to just start the process to schedule people. Not everyone knows the insurance process better than the people that used to actually do it for a living. I call BS. Don't do it. Don't even waste your time and ask your sleep doctor to go to a different facility not tied to JIVA or Dr. McDannald. Run from these providers.

I was able to pick up the at home sleep study test kit in a few days, and the in-office instructions on set-up and use were decent enough once I supplemented that with a quick YouTube online search on proper use for a successful test and data entry into the equipment. But then the wheels came off! I dropped the kit off to Dr. Nathan's office as promised the very next morning before 11 AM. I was told that due to the holidays, it would Nathan up to two weeks to view the data and write the report of my sleep study to my John Muir primary care doctor. I was told that the study and the data held in the device was quite good and I could expect the report in due course and timely. It has now been three weeks since the device was returned and the data entered into Dr. Nathan's office based system, but I have no report whatsoever, no response to my inquiries, and even telephone calls from my primary care doctor to Dr. Nathan (that apparently owns a financial interest in this sleep clinic) have been totally ignored. There is no justifiable reason why Dr. Nathan should take three weeks to compile what is almost certainly a machine-based standard report based on the electronic data downloaded from the sleep study device. The delay is bad enough, but being completely ignored is perplexing and very disappointing. I will not return to this clinic and I would not recommend it based on my experience over these last three weeks.
