Kind Words From Peter’s Clients

“Forever grateful to Peter, Mary and staff. Peter has always been there for me, providing an abundance of knowledge, understanding and support. Most of all with so much compassion and kindness. So blessed to have found Peter all those years ago (early 2000’s)” (Nicholas)

“Peter listened to my long list of issues without rushing me and explained the process in detail.

Looking forward to my next appointment!”

“We have a 3 1/2 year old daughter with horrendous eczema on her arms and legs, to the point we would wake up and all four limbs bleeding due to Aria scratching through the night.

Was referred to Western medicine three visits to dermatologist, to identify what the cause was and only told apply cream she will grow out of it at the age of 7 – 200 bucks .

Three visits and 600 bucks later no results. Daughter is now getting very upset and arms and legs getting worse.

Then we saw Peter and Dayna at Mullen health, these people changed our daughters life.

1 blood test, a consult a week later, and in 4 days Arias life had changed. Diet and food related in tolerances was causing the eczema to go crazy!

Please if your child is having the same problems or similar issues, please don’t wait to see the team at Mullen health you won’t regret it .” (Jai)

“Getting my health under control with my naturopath THE Peter Mullen from Mullen Natrural Health Center in Newcastle.
I admit I was a bit starstuck during our appointment. He is a wealth of knowledge, and I think he is Australia’s best naturopath out there! ( this could be a fact? Haha)

I love GP doctors as well, don’t get me wrong they have their place. But I think a lot of what’s wrong with us these days can be helped naturally with vitamins, supplements and a healthy diet. Dr. Peter Mullen has been helping me get on the right track to fix certain health issues in my life, some that I’ve had for 14 years!
Gut issues, fatigued, mouth sores, anxiety etc should not be a part of your day to day life.
The ongoing support you get from Dr.Mullen as well is extraordinary! I’ve received emails of more tips and encouragement to continue on this road to recovery and healing. Also you can call and have more questions answered in between appointments. Did I mention appointments are 1 hour long, where he genuinely goes into detail with ALL your issues.
It’s not a quick 15 minute in and out kind of thing where you can’t even go in to details of your issues. There is genuine care and a want to see you improve naturally!
Dr Mullen is very thorough . His approach is not to just treat the symptoms of the issues but to get down to the root cause and understand why you’re experiencing the things you do . I appreciate not bandaiding problems but truly solving them.
If you live in the Newcastle area or even NSW, I highly highly recommend Mullen Natural Health Center!” ( Teryn)

“Peter Mullen is incredibly generous with his time, knowledgeable in his health field and super supportive of his patients. He has helped me immensely over the past 3 years and I am very grateful for his guidance and input into my health and wellbeing. Mary and Dayna at reception are lovely too and always remember everyone’s name. I highly recommend Mullens as an alternative to mainstream medical treatment, which failed me time and time again.” (WW,Newcastle)

“For years I had put up with constant headaches, nausea, tiredness, body aches & pains, bloating, constipation, diarrhoea & other health issues but my GP could find nothing “wrong” with me. So I thought ok well I must just be getting old. But I reached a point at the end of October, 2013 where I thought enough is enough. My health was deteriorating further & my weight had ballooned. I was 41 years old but felt at least 80 & honestly believed that I would not be in this world for much longer if I continued on this same path. So I commenced my journey to feel well again with my first appointment with Peter on the 6th November, 2013. I set off to my appointment with an open mind & a willingness to do whatever was needed to feel better again & from the moment I stepped through the door at Mullen Natural Health I knew I had made the right decision. Peter & his team were so welcoming & I immediately felt comfortable, at ease & like I had known them for years. Peter got straight down to diagnosing the underlaying reasons causing my health issues & put me on the path to helping my body heal & to function correctly. I was so relieved to finally have some answers & amazed that all I needed to do was make some dietary & lifestyle changes. At that first appointment I weighed in at almost 90kg & now 15 months later I am 63kg & to say I feel well again is an understatement. I feel absolutely amazing & like a completely different woman – full of energy & a joy for life & I actually feel young again! I am so grateful for the friendly professionalism, support, knowledge & guidance Peter & his team have given me throughout my journey & I could never thank them enough for helping me to regain my health & ultimately my life back.” (TB, Branxton)

“Peter was an integral part of my son’s life for a few years while getting his immune system operating to its optimum. Before seeing Peter my son was having episodes where he had up to one week off school and would lay on the lounge with no energy. Seeing Peter gave him every opportunity to reach his potential in all areas. His health is the best it has been in two years, his confidence has improved and he has done extremely well with his results in Year 12 and has now gone on to university. Peter was a mentor to my son. He enjoyed his regular visits to Peter and felt valued by him. With Peter’s help my son was able to gain some insight into his own health and well-being and knows that he still needs to look after himself. He is aware of his body’s limits and makes decisions accordingly. Thank you Peter for your wonderful work and commitment to my son.” (BP, Leichardt)

“Excellent, he listens to what I have to say, provides advice on what I should be doing based on my concerns and doesn’t rush you if you need to talk. Treats you as a person and not a number. “(Anonymous)

“I have been seen by Peter at both Singleton and Murray Street and have established a good rapport with him over those times. I am happy to report that I enjoy good health and have been supported in this by his choice of suitable supplements specific to my body’s requirements. My adverse comment has to do with the high price of supplements and consultation charges which are a challenge for me as a pensioner to meet sometimes.” (Mary)

“I saw Peter for the first time a couple of weeks ago. I was immediately comfortable with chatting to him about all my heath concerns. He is so knowledgable and look forward to a continued journey together on achieving better health for myself.” (Megan)

“Goodaye, I’ve been helped by Peter for a long time and I am now retired but I started when I was having irritable bowel syndrome (IBS) problems. Of course this will seem personal, but what is NOT personal about your health! After some help in both analysis of urine etc a blood test or two (including a live blood test) and mineral supplementation, I find myself feeling heaps better. So I got my beautiful wife to come in and the rest is history. I have my IBS under control, I have more energy and I still have regular checks with this wonderful man and all of his staff. You become part of the Mullen Health family and enjoy life more. Some of my friends have said things like “oh what a waste of time, why not just take a good vitamin pill daily, exercise, it’ll do the same thing?” Well I tried their advice for a while and guess what my symptoms returned, and so did I to Mullen Health. The amazing changes have been – clearer skin; no tummy bloating if I behave myself; advice on stress levels shown via him looking deeply into my eyes & saying OK this is showing etc through his Iridology expertise; general health via blood pressure and pulse checking AND keeping records to encourage or “chastise” when I’ve obviously been naughty. Anyway we are very happy with our care we get from Mullen Health.” (Allan)
